To examine the role of GCs in spatial coding, we measured excitatory postsynaptic potentials (EPSPs) and action potentials (APs) in head-fixed mice running on a linear belt. Intracellular recording from morphologically identified GCs revealed that most cells were active, but activity level varied over a wide range. Whereas only ∼5% of GCs showed spatially tuned spiking, ∼50% received spatially tuned input. Thus, the GC population broadly encodes spatial information, but only a subset relays this information to the CA3 network. Fourier analysis indicated that GCs received conjunctive place-grid-like synaptic input, suggesting code conversion in single neurons. GC firing was correlated with dendritic complexity and intrinsic excitability, but not extrinsic excitatory input or dendritic cable properties. Thus, functional maturation may control input-output transformation and spatial code conversion.","lang":"eng"}],"acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program (grant agreement 692692, P.J.) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award, P.J.).

Lossy compression of data is an intriguing solution, but comes with its own drawbacks, such as potential signal loss, and the need for careful optimization of the compression ratio. In this work, we focus on a setting where this problem is especially acute: compressive sensing frameworks for interferometry and medical imaging. We ask the following question: can the precision of the data representation be lowered for all inputs, with recovery guarantees and practical performance Our first contribution is a theoretical analysis of the normalized Iterative Hard Thresholding (IHT) algorithm when all input data, meaning both the measurement matrix and the observation vector are quantized aggressively. We present a variant of low precision normalized IHT that, under mild conditions, can still provide recovery guarantees. The second contribution is the application of our quantization framework to radio astronomy and magnetic resonance imaging. We show that lowering the precision of the data can significantly accelerate image recovery. We evaluate our approach on telescope data and samples of brain images using CPU and FPGA implementations achieving up to a 9x speedup with negligible loss of recovery quality.","lang":"eng"}]},{"year":"2020","language":[{"iso":"eng"}],"OA_place":"publisher","oa":1,"intvolume":"        13","volume":13,"publication":"Molecular Plant","day":"07","acknowledgement":"We thank Dr. Gai Huang for his comments and help.

Here, we present the structure of the Mrp complex from Anoxybacillus flavithermus solved by cryo-EM at 3.0 Å resolution. It is a dimer of seven-subunit protomers with 50 trans-membrane helices each. Surface charge distribution within each monomer is remarkably asymmetric, revealing probable proton and sodium translocation pathways. On the basis of the structure we propose a mechanism where the coupling between sodium and proton translocation is facilitated by a series of electrostatic interactions between a cation and key charged residues. This mechanism is likely to be applicable to the entire family of redox proton pumps, where electron transfer to substrates replaces cation movements.","lang":"eng"}],"related_material":{"record":[{"relation":"dissertation_contains","id":"8353","status":"public"}],"link":[{"description":"News on IST Homepage","relation":"press_release","url":"https://ist.ac.at/en/news/mystery-of-giant-proton-pump-solved/"}]},"month":"07","external_id":{"isi":["000562123600001"],"pmid":["32735215"]},"type":"journal_article","oa_version":"Published Version","fulldoi":"https://doi.org/10.7554/eLife.59407","date_updated":"2026-04-08T07:23:36Z","publication_status":"published","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","article_number":"e59407","license":"https://creativecommons.org/licenses/by/4.0/","pmid":1,"department":[{"_id":"LeSa"}],"has_accepted_license":"1","article_processing_charge":"No"},{"conference":{"end_date":"2020-09-25","start_date":"2020-09-20","name":"EMSOFT: Embedded Software","location":"Virtual "},"oa":1,"year":"2020","language":[{"iso":"eng"}],"day":"01","arxiv":1,"publication":"Proceedings of the International Conference on Embedded Software","title":"Reachability analysis of linear hybrid systems via block decomposition","quality_controlled":"1","author":[{"full_name":"Bogomolov, Sergiy","last_name":"Bogomolov","first_name":"Sergiy"},{"first_name":"Marcelo","full_name":"Forets, Marcelo","last_name":"Forets"},{"full_name":"Frehse, Goran","last_name":"Frehse","first_name":"Goran"},{"last_name":"Potomkin","full_name":"Potomkin, Kostiantyn","first_name":"Kostiantyn"},{"full_name":"Schilling, Christian","id":"3A2F4DCE-F248-11E8-B48F-1D18A9856A87","last_name":"Schilling","first_name":"Christian","orcid":"0000-0003-3658-1065"}],"file":[{"file_id":"8288","access_level":"open_access","creator":"cschilli","relation":"main_file","success":1,"checksum":"d19e97d0f8a3a441dc078ec812297d75","content_type":"application/pdf","date_updated":"2020-08-24T12:53:15Z","date_created":"2020-08-24T12:53:15Z","file_name":"2020EMSOFT.pdf","file_size":696384}],"file_date_updated":"2020-08-24T12:53:15Z","_id":"8287","date_created":"2020-08-24T12:56:20Z","article_processing_charge":"No","has_accepted_license":"1","department":[{"_id":"ToHe"}],"keyword":["reachability","hybrid systems","decomposition"],"ec_funded":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication_status":"published","date_updated":"2026-04-03T09:32:00Z","oa_version":"Preprint","type":"conference","external_id":{"arxiv":["1905.02458"],"isi":["000587712700072"]},"month":"10","related_material":{"record":[{"status":"public","id":"8790","relation":"later_version"}]},"abstract":[{"text":"Reachability analysis aims at identifying states reachable by a system within a given time horizon.

In this paper, we enhance both of these operators and make sure that most of the involved computations are performed in low-dimensional state space. In particular, we improve the continuous-post operator by performing computations in high-dimensional state space only for time intervals relevant for the subsequent application of the discrete-post operator. Furthermore, the new discrete-post operator performs low-dimensional computations by leveraging the structure of the guard and assignment of a considered transition. We illustrate the potential of our approach on a number of challenging benchmarks.","lang":"eng"}],"project":[{"grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","_id":"25C5A090-B435-11E9-9278-68D0E5697425","name":"Synaptic communication in neuronal microcircuits","grant_number":"Z00312"},{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"status":"public","isi":1,"date_published":"2020-10-01T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"ddc":["000"],"citation":{"mla":"Bogomolov, Sergiy, et al. “Reachability Analysis of Linear Hybrid Systems via Block Decomposition.” <i>Proceedings of the International Conference on Embedded Software</i>, 2020.","apa":"Bogomolov, S., Forets, M., Frehse, G., Potomkin, K., &#38; Schilling, C.

The breakdown of thermalization may be complete, when all eigenstates in the many-body spectrum become localized, or partial, when the so-called many-body mobility edge separates localized and delocalized parts of the spectrum. Previously, De Roeck et al. [Phys. Rev. B 93, 014203 (2016)] suggested a possible instability of the many-body mobility edge in energy density. The local ergodic regions—so-called “bubbles”—resonantly spread throughout the system, leading to delocalization. In order to study such instability mechanism, in this work we design a model featuring many-body mobility edge in particle density: the states at small particle density are localized, while increasing the density of particles leads to delocalization. Using numerical simulations with matrix product states, we demonstrate the stability of many-body localization with respect to small bubbles in large dilute systems for experimentally relevant timescales. In addition, we demonstrate that processes where the bubble spreads are favored over processes that lead to resonant tunneling, suggesting a possible mechanism behind the observed stability of many-body mobility edge. We conclude by proposing experiments to probe particle density mobility edge in the Bose-Hubbard model."}],"oa_version":"Preprint","type":"journal_article","external_id":{"isi":["000562628300001"],"arxiv":["2005.02999"]},"ec_funded":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","issue":"6","fulldoi":"https://doi.org/10.1103/physrevb.102.060202","date_updated":"2026-04-07T13:26:31Z","article_number":"060202(R)","article_processing_charge":"No","has_accepted_license":"1","department":[{"_id":"MaSe"}]},{"issue":"1","publication_status":"published","date_updated":"2026-04-02T14:36:31Z","fulldoi":"https://doi.org/10.1038/s41467-020-17957-0","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","department":[{"_id":"LeSa"}],"article_processing_charge":"No","has_accepted_license":"1","article_number":"4135","pmid":1,"doi":"10.1038/s41467-020-17957-0","isi":1,"status":"public","citation":{"apa":"Gutierrez-Fernandez, J., Kaszuba, K., Minhas, G.

We also determined cryo-EM structures of major and minor native states of the complex, differing in the position of the peripheral arm. Crystal structures show that binding of quinone-like compounds (but not of NADH) leads to a related global conformational change, accompanied by local re-arrangements propagating from the quinone site to the nearest proton channel.

Nevertheless, in recent years several artificial base pairs have been developed in attempts to expand the genetic code. Employment of these additional base pairs increases the information capacity and variety of DNA sequences, and provides a platform for the site-specific, enzymatic incorporation of extra functional components into DNA and RNA. As a result, of the development of such expanded systems, many artificial base pairs have been synthesized and tested under various conditions. Following many stages of enhancement, unnatural base pairs have been modified to eliminate their weak points, qualifying them for specific research needs.

Nevertheless, in recent years several artificial base pairs have been developed in attempts to expand the genetic code. Employment of these additional base pairs increases the information capacity and variety of DNA sequences, and provides a platform for the site-specific, enzymatic incorporation of extra functional components into DNA and RNA. As a result, of the development of such expanded systems, many artificial base pairs have been synthesized and tested under various conditions. Following many stages of enhancement, unnatural base pairs have been modified to eliminate their weak points, qualifying them for specific research needs.

For probabilistic programs the notion is naturally extended to expected sensitivity. A previous approach develops a relational program logic framework for proving expected sensitivity of probabilistic while loops, where the number of iterations is fixed and bounded. In this work, we consider probabilistic while loops where the number of iterations is not fixed, but randomized and depends on the initial input values. We present a sound approach for proving expected sensitivity of such programs. Our sound approach is martingale-based and can be automated through existing martingale-synthesis algorithms. Furthermore, our approach is compositional for sequential composition of while loops under a mild side condition. We demonstrate the effectiveness of our approach on several classical examples from Gambler's Ruin, stochastic hybrid systems and stochastic gradient descent. We also present experimental results showing that our automated approach can handle various probabilistic programs in the literature."}],"oa_version":"Published Version","type":"conference","external_id":{"arxiv":["1902.04744"]},"date_published":"2020-01-01T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"citation":{"apa":"Wang, P., Fu, H., Chatterjee, K., Deng, Y., &#38; Xu, M.

This is due to the sheer number of possible interleavings of a concurrent program, all of which have to be tracked and accounted for in a formal proof. Inventing an inductive invariant that captures all interleavings of a low-level implementation is theoretically possible, but practically intractable. We develop a refinement-based verification framework that provides mechanisms to simplify proof construction by decomposing the verification task into smaller subtasks.\r\n\r\nIn a first line of work, we present a foundation for refinement reasoning over structured concurrent programs. We introduce layered concurrent programs as a compact notation to represent multi-layer refinement proofs. A layered concurrent program specifies a sequence of connected concurrent programs, from most concrete to most abstract, such that common parts of different programs are written exactly once. Each program in this sequence is expressed as structured concurrent program, i.e., a program over (potentially recursive) procedures, imperative control flow, gated atomic actions, structured parallelism, and asynchronous concurrency. This is in contrast to existing refinement-based verifiers, which represent concurrent systems as flat transition relations. We present a powerful refinement proof rule that decomposes refinement checking over structured programs into modular verification conditions. Refinement checking is supported by a new form of modular, parameterized invariants, called yield invariants, and a linear permission system to enhance local reasoning.\r\n\r\nIn a second line of work, we present two new reduction-based program transformations that target asynchronous programs. These transformations reduce the number of interleavings that need to be considered, thus reducing the complexity of invariants. Synchronization simplifies the verification of asynchronous programs by introducing the fiction, for proof purposes, that asynchronous operations complete synchronously. Synchronization summarizes an asynchronous computation as immediate atomic effect. Inductive sequentialization establishes sequential reductions that captures every behavior of the original program up to reordering of coarse-grained commutative actions. A sequential reduction of a concurrent program is easy to reason about since it corresponds to a simple execution of the program in an idealized synchronous environment, where processes act in a fixed order and at the same speed.\r\n\r\nOur approach is implemented the CIVL verifier, which has been successfully used for the verification of several complex concurrent programs. In our methodology, the overall correctness of a program is established piecemeal by focusing on the invariant required for each refinement step separately. While the programmer does the creative work of specifying the chain of programs and the inductive invariant justifying each link in the chain, the tool automatically constructs the verification conditions underlying each refinement step."}],"month":"09","type":"dissertation","oa_version":"Published Version"},{"publication":"Nature Communications","volume":11,"day":"27","acknowledgement":"This paper is dedicated to deceased P.

Although their Histidine Kinase receptors are substantially localised to the endoplasmic reticulum, cellular sites of cytokinin perception and importance of spatially heterogeneous cytokinin distribution continue to be debated. Here we show that cytokinin perception by plasma membrane receptors is an effective additional path for cytokinin response. Readout from a Two Component Signalling cytokinin-specific reporter (TCSn::GFP) closely matches intracellular cytokinin content in roots, yet we also find cytokinins in extracellular fluid, potentially enabling action at the cell surface. Cytokinins covalently linked to beads that could not pass the plasma membrane increased expression of both TCSn::GFP and Cytokinin Response Factors. Super-resolution microscopy of GFP-labelled receptors and diminished TCSn::GFP response to immobilised cytokinins in cytokinin receptor mutants, further indicate that receptors can function at the cell surface. We argue that dual intracellular and surface locations may augment flexibility of cytokinin responses.","lang":"eng"}],"ec_funded":1,"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","publication_status":"published","fulldoi":"https://doi.org/10.1038/s41467-020-17700-9","date_updated":"2026-04-03T09:25:48Z","article_processing_charge":"No","has_accepted_license":"1","department":[{"_id":"JiFr"}],"pmid":1,"article_number":"4284","file_date_updated":"2020-12-10T12:23:56Z","date_created":"2020-09-06T22:01:13Z","_id":"8337","title":"Cell-surface receptors enable perception of extracellular cytokinins","quality_controlled":"1","article_type":"original","author":[{"first_name":"Ioanna","full_name":"Antoniadi, Ioanna","last_name":"Antoniadi"},{"first_name":"Ondřej","full_name":"Novák, Ondřej","last_name":"Novák"},{"id":"0AE74790-0E0B-11E9-ABC7-1ACFE5697425","last_name":"Gelová","full_name":"Gelová, Zuzana","first_name":"Zuzana","orcid":"0000-0003-4783-1752"},{"full_name":"Johnson, Alexander J","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87","last_name":"Johnson","orcid":"0000-0002-2739-8843","first_name":"Alexander J"},{"first_name":"Ondřej","last_name":"Plíhal","full_name":"Plíhal, Ondřej"},{"first_name":"Radim","full_name":"Simerský, Radim","last_name":"Simerský"},{"first_name":"Václav","full_name":"Mik, Václav","last_name":"Mik"},{"last_name":"Vain","full_name":"Vain, Thomas","first_name":"Thomas"},{"first_name":"Eduardo","full_name":"Mateo-Bonmatí, Eduardo","last_name":"Mateo-Bonmatí"},{"full_name":"Karady, Michal","last_name":"Karady","first_name":"Michal"},{"first_name":"Markéta","last_name":"Pernisová","full_name":"Pernisová, Markéta"},{"first_name":"Lenka","last_name":"Plačková","full_name":"Plačková, Lenka"},{"first_name":"Korawit","full_name":"Opassathian, Korawit","last_name":"Opassathian"},{"first_name":"Jan","full_name":"Hejátko, Jan","last_name":"Hejátko"},{"first_name":"Stéphanie","last_name":"Robert","full_name":"Robert, Stéphanie"},{"orcid":"0000-0002-8302-7596","first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří","last_name":"Friml"},{"first_name":"Karel","full_name":"Doležal, Karel","last_name":"Doležal"},{"first_name":"Karin","full_name":"Ljung, Karin","last_name":"Ljung"},{"last_name":"Turnbull","full_name":"Turnbull, Colin","first_name":"Colin"}],"publication_identifier":{"eissn":["2041-1723"]},"publisher":"Springer Nature","file":[{"access_level":"open_access","file_id":"8936","relation":"main_file","creator":"dernst","checksum":"5b96f39b598de7510cfefefb819b9a6d","success":1,"date_created":"2020-12-10T12:23:56Z","file_name":"2020_NatureComm_Antoniadi.pdf","date_updated":"2020-12-10T12:23:56Z","content_type":"application/pdf","file_size":3526415}],"scopus_import":"1","acknowledgement":"We thank Bruno Müller and Aaron Rashotte for critical discussions and provision of plant lines used in this work, Roger Granbom and Tamara Hernández Verdeja (UPSC, Umeå, Sweden) for technical assistance and providing materials, Zuzana Pěkná and Karolina Wojewodová (CRH, Palacký University, Olomouc, Czech Republic) for help with cytokinin receptor binding assays, and David Zalabák (CRH, Palacký University, Olomouc, Czech Republic) for provision of vector pINIIIΔEH expressing CRE1/AHK4.

The literature contains a wealth of useful theorems about the behavior of discrete Gaussians under convolutions and related operations. Yet despite their structural similarities, most of these theorems are formally incomparable, and their proofs tend to be monolithic and written nearly “from scratch,” making them unnecessarily hard to verify, understand, and extend.\r\nIn this work we present a modular framework for analyzing linear operations on discrete Gaussian distributions. The framework abstracts away the particulars of Gaussians, and usually reduces proofs to the choice of appropriate linear transformations and elementary linear algebra. To showcase the approach, we establish several general properties of discrete Gaussians, and show how to obtain all prior convolution theorems (along with some new ones) as straightforward corollaries. As another application, we describe a self-reduction for Learning With Errors (LWE) that uses a fixed number of samples to generate an unlimited number of additional ones (having somewhat larger error). The distinguishing features of our reduction are its simple analysis in our framework, and its exclusive use of discrete Gaussians without any loss in parameters relative to a prior mixed discrete-and-continuous approach.\r\nAs a contribution of independent interest, for subgaussian random matrices we prove a singular value concentration bound with explicitly stated constants, and we give tighter heuristics for specific distributions that are commonly used for generating lattice trapdoors. These bounds yield improvements in the concrete bit-security estimates for trapdoor lattice cryptosystems."}],"month":"05","day":"15","volume":12110,"publication":"23rd IACR International Conference on the Practice and Theory of Public-Key Cryptography","intvolume":"     12110","oa":1,"conference":{"start_date":"2020-05-04","end_date":"2020-05-07","location":"Edinburgh, United Kingdom","name":"PKC: Public-Key Cryptography"},"language":[{"iso":"eng"}],"year":"2020","_id":"8339","page":"623-651","date_created":"2020-09-06T22:01:13Z","author":[{"last_name":"Genise","full_name":"Genise, Nicholas","first_name":"Nicholas"},{"last_name":"Micciancio","full_name":"Micciancio, Daniele","first_name":"Daniele"},{"last_name":"Peikert","full_name":"Peikert, Chris","first_name":"Chris"},{"id":"488F98B0-F248-11E8-B48F-1D18A9856A87","last_name":"Walter","full_name":"Walter, Michael","first_name":"Michael","orcid":"0000-0003-3186-2482"}],"quality_controlled":"1","title":"Improved discrete Gaussian and subgaussian analysis for lattice cryptography","scopus_import":"1","publisher":"Springer Nature","publication_identifier":{"eissn":["1611-3349"],"issn":["0302-9743"],"isbn":["9783030453732"]}},{"day":"08","degree_awarded":"PhD","acknowledgement":"My thanks goes to the Loose lab members, BioImaging, Life Science and Nanofabrication Facilities and the wonderful international community at IST for sharing this experience with me.","language":[{"iso":"eng"}],"corr_author":"1","OA_place":"publisher","year":"2020","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"NanoFab"}],"supervisor":[{"full_name":"Loose, Martin","id":"462D4284-F248-11E8-B48F-1D18A9856A87","last_name":"Loose","first_name":"Martin","orcid":"0000-0001-7309-9724"}],"oa":1,"_id":"8341","date_created":"2020-09-08T08:53:53Z","page":"215","file_date_updated":"2021-09-16T12:49:12Z","file":[{"creator":"dernst","relation":"source_file","file_id":"8342","access_level":"closed","checksum":"70871b335a595252a66c6bbf0824fb02","file_size":65246782,"content_type":"application/x-zip-compressed","date_created":"2020-09-08T09:00:29Z","date_updated":"2021-09-16T12:49:12Z","file_name":"2020_Urban_Bezeljak_Thesis_TeX.zip"},{"file_size":31259058,"content_type":"application/pdf","date_updated":"2021-09-16T12:49:12Z","file_name":"2020_Urban_Bezeljak_Thesis.pdf","date_created":"2020-09-08T09:00:27Z","checksum":"59a62275088b00b7241e6ff4136434c7","creator":"dernst","relation":"main_file","file_id":"8343","access_level":"open_access"}],"publisher":"Institute of Science and Technology Austria","publication_identifier":{"issn":["2663-337X"]},"author":[{"orcid":"0000-0003-1365-5631","first_name":"Urban","last_name":"Bezeljak","full_name":"Bezeljak, Urban","id":"2A58201A-F248-11E8-B48F-1D18A9856A87"}],"title":"In vitro reconstitution of a Rab activation switch","date_updated":"2026-04-08T07:24:56Z","fulldoi":"https://doi.org/10.15479/AT:ISTA:8341","publication_status":"published","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","alternative_title":["ISTA Thesis"],"department":[{"_id":"MaLo"}],"has_accepted_license":"1","article_processing_charge":"No","ddc":["570"],"citation":{"apa":"Bezeljak, U.

Each of these membrane-enclosed compartments has a distinct composition of lipids and proteins, which is essential for accurate membrane traffic and homeostasis. Interestingly, their biochemical identities are achieved with the help\r\nof small GTPases of the Rab family, which cycle between GDP- and GTP-bound forms on the selected membrane surface. While this activity switch is well understood for an individual protein, how Rab GTPases collectively transition between states to generate decisive signal propagation in space and time is unclear. In my PhD thesis, I present\r\nin vitro reconstitution experiments with theoretical modeling to systematically study a minimal Rab5 activation network from bottom-up. We find that positive feedback based on known molecular interactions gives rise to bistable GTPase activity switching on system’s scale. Furthermore, we determine that collective transition near the critical\r\npoint is intrinsically stochastic and provide evidence that the inactive Rab5 abundance on the membrane can shape the network response. Finally, we demonstrate that collective switching can spread on the lipid bilayer as a traveling activation wave, representing a possible emergent activity pattern in endosomal maturation. Together, our\r\nfindings reveal new insights into the self-organization properties of signaling networks away from chemical equilibrium. Our work highlights the importance of systematic characterization of biochemical systems in well-defined physiological conditions. This way, we were able to answer long-standing open questions in the field and close the gap between regulatory processes on a molecular scale and emergent responses on system’s level.","lang":"eng"}],"related_material":{"record":[{"id":"7580","status":"public","relation":"part_of_dissertation"}]},"month":"09","type":"dissertation","oa_version":"Published Version"},{"oa":1,"supervisor":[{"first_name":"Leonid A","orcid":"0000-0002-0977-7989","last_name":"Sazanov","full_name":"Sazanov, Leonid A","id":"338D39FE-F248-11E8-B48F-1D18A9856A87"}],"OA_place":"publisher","corr_author":"1","language":[{"iso":"eng"}],"year":"2020","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"EM-Fac"},{"_id":"ScienComp"}],"acknowledgement":"I acknowledge the scientific service units of the IST Austria for providing resources by the Life Science Facility, the Electron Microscopy Facility and the high-performance computer cluster.

Mrp antiporters are unique in a way that they are composed of seven subunits (MrpABCDEFG) encoded in a single operon, whereas other antiporters catalyzing the same reaction are mostly encoded by a single gene. Mrp exchangers are crucial for intracellular pH homeostasis and Na+ efflux, essential mechanisms for H+ uptake under alkaline environments and for reduction of the intracellular concentration of toxic cations. Mrp displays no homology to any other monovalent Na+(K+)/H+ antiporters but Mrp subunits have primary sequence similarity to essential redox-driven proton pumps, such as respiratory complex I and membrane-bound hydrogenases. This similarity reinforces the hypothesis that these present day redox-driven proton pumps are descended from the Mrp antiporter. The Mrp structure serves as a model to understand the yet obscure coupling mechanism between ion or electron transfer and proton translocation in this large group of proteins. In the thesis, I am presenting the purification, biochemical analysis, cryo-EM analysis and molecular structure of the Mrp complex from Anoxybacillus flavithermus solved by cryo-EM at 3.0 Å resolution. Numerous conditions were screened to purify Mrp to high homogeneity and to obtain an appropriate distribution of single particles on cryo-EM grids covered with a continuous layer of ultrathin carbon. A preferred particle orientation problem was solved by performing a tilted data collection. The activity assays showed the specific pH-dependent\r\nprofile of secondary active antiporters. The molecular structure shows that Mrp is a dimer of seven-subunit protomers with 50 trans-membrane helices each. The dimer interface is built by many short and tilted transmembrane helices, probably causing a thinning of the bacterial membrane. The surface charge distribution shows an extraordinary asymmetry within each monomer, revealing presumable proton and sodium translocation pathways. The two largest\r\nand homologous Mrp subunits MrpA and MrpD probably translocate one proton each into the cell. The sodium ion is likely being translocated in the opposite direction within the small subunits along a ladder of charged and conserved residues. Based on the structure, we propose a mechanism were the antiport activity is accomplished via electrostatic interactions between the charged cations and key charged residues. The flexible key TM helices coordinate these\r\nelectrostatic interactions, while the membrane thinning between the monomers enables the translocation of sodium across the charged membrane. The entire family of redox-driven proton pumps is likely to perform their mechanism in a likewise manner.","lang":"eng"}],"month":"09","doi":"10.15479/AT:ISTA:8353","status":"public","project":[{"_id":"26169496-B435-11E9-9278-68D0E5697425","grant_number":"24741","name":"Revealing the functional mechanism of Mrp antiporter, an ancestor of complex I"}],"citation":{"short":"J.
