We demonstrate that a CPMAS CryoProbe yields ca. 8-fold increased signal-to-noise over a room-temperature probe, or a ca. 3-4-fold larger per-mass sensitivity. The increased sensitivity allowed to obtain high-resolution spectra even on intact bacteria. Moreover, we compare resolution and sensitivity of 1H MAS experiments obtained at 100 kHz vs. 55 kHz.

VACV is a valuable model for studying large pleomorphic DNA viruses in general and poxviruses specifically, as many features, such as core morphology and structural proteins, are well conserved within this family. Despite decades of research, our understanding of the structural components and proteins that comprise the poxvirus core in mature virions remains limited. Although major core proteins were identified via indirect experimental evidence, the core's complexity, with its large size, structure and number of involved proteins, has hindered efforts to achieve high-resolution insights and to define the roles of the individual proteins. The specific protein composition of the core's individual layers, including the palisade layer and the inner core wall, has remained unclear. In this study, we have merged multiple approaches, including single particle cryo electron microscopy of purified virus cores, cryo-electron tomography and subtomogram averaging of mature virions and molecular modeling to elucidate the structural determinants of the VACV core. Due to the lack of experimentally derived structures, either in situ or reconstituted in vitro, we used Alphafold to predict models of the putative major core protein candidates, A10, 23k, A3, A4, and L4. Our results show that the VACV core is composed of several layers with varying local symmetries, forming more intricate interactions than observed previously. This allowed us to identify several molecular building blocks forming the viral core lattice. In particular, we identified trimers of protein A10 as a major core structure that forms the palisade layer of the viral core. Additionally, we revealed that six petals of a flower shaped core pore within the core wall are composed of A10 trimers. Furthermore, we obtained a cryo-EM density for the inner core wall that could potentially accommodate an A3 dimer. Integrating descriptions of protein interactions from previous studies enabled us to provide a detailed structural model of the poxvirus core wall, and our findings indicate that the interactions within A10 trimers are likely consistent across orthopox- and parapoxviruses. This combined application of cryo-SPA and cryo-ET can help overcome obstacles in studying complex virus structures in the future, including their key assembly proteins, interactions, and the formation into a core lattice. Our work provides important fundamental new insights into poxvirus core architecture, also considering the recent re-emergence of poxviruses."}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"LifeSc"},{"_id":"ScienComp"}],"day":"30","degree_awarded":"PhD","month":"12","corr_author":"1","publisher":"Institute of Science and Technology Austria","year":"2024","project":[{"_id":"26736D6A-B435-11E9-9278-68D0E5697425","grant_number":"P31445","call_identifier":"FWF","name":"Structural conservation and diversity in retroviral capsid"}],"type":"dissertation","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"keyword":["cryo-EM","cryo-ET","cryo-SPA","Structural Virology","Poxvirus","Vaccinia Virus","Structural Biology"],"department":[{"_id":"GradSch"},{"_id":"FlSc"}],"has_accepted_license":"1","article_processing_charge":"No","status":"public","ddc":["570"],"date_updated":"2026-04-07T12:59:44Z","file":[{"date_updated":"2025-01-07T12:15:11Z","file_size":38814932,"content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","file_id":"18769","file_name":"PhD_thesis_Julia_Datler.docx","checksum":"3e51cab327c754045c3d29c1a50cc9a9","date_created":"2025-01-07T12:15:11Z","creator":"jstanger","access_level":"closed","relation":"source_file"},{"date_updated":"2025-01-07T12:15:14Z","file_size":12044865,"content_type":"application/pdf","success":1,"file_id":"18770","date_created":"2025-01-07T12:15:14Z","file_name":"PhD_thesis_Julia_Datler.pdf","checksum":"22fabe5b97950bf852212f6edb555173","creator":"jstanger","access_level":"open_access","relation":"main_file"}],"language":[{"iso":"eng"}],"related_material":{"record":[{"id":"12334","status":"public","relation":"part_of_dissertation"},{"status":"public","id":"14979","relation":"part_of_dissertation"}]}},{"pmid":1,"abstract":[{"text":"Poxviruses are among the largest double-stranded DNA viruses, with members such as variola virus, monkeypox virus and the vaccination strain vaccinia virus (VACV).

Hence, which proteins constitute which layers of the core, such as the palisade layer and the inner core wall, has remained enigmatic. Here we show, using a multi-modal cryo-electron microscopy (cryo-EM) approach in combination with AlphaFold molecular modeling, that trimers formed by the cleavage product of VACV protein A10 are the key component of the palisade layer. This allows us to place previously obtained descriptions of protein interactions within the core wall into perspective and to provide a detailed model of poxvirus core architecture.

Inherently invisible to crystallography, aromatic motions have been primarily studied by solution NMR. The question how packing of proteins in crystals affects ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a protein in three different crystal packing environments to shed light onto possible impact of packing on ring flips. The flips of the two Phe residues in ubiquitin, both surface exposed, appear remarkably conserved in the different crystal forms, even though the intermolecular packing is quite different: Phe4 flips on a ca. 10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to µs motion. Our findings suggest that intramolecular influences are more important for ring flips than intermolecular (packing) effects.","lang":"eng"}],"pmid":1,"day":"01","publisher":"Elsevier","month":"01","corr_author":"1","type":"journal_article","year":"2023","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"keyword":["Structural Biology"],"article_processing_charge":"No","department":[{"_id":"PaSc"}],"has_accepted_license":"1","publication":"Journal of Structural Biology: X","article_number":"100079","external_id":{"pmid":["36578472"]},"status":"public","file":[{"relation":"main_file","date_created":"2023-08-16T09:36:28Z","file_name":"2023_JourStrucBiologyX_Gauto.pdf","checksum":"b4b1c10a31018aafe053b7d55a470e54","file_id":"14064","creator":"dernst","access_level":"open_access","date_updated":"2023-08-16T09:36:28Z","file_size":5132322,"content_type":"application/pdf","success":1}],"date_updated":"2024-10-09T21:04:02Z","ddc":["570"],"language":[{"iso":"eng"}]},{"quality_controlled":"1","file_date_updated":"2023-08-16T08:31:04Z","page":"762-777","publication_status":"published","oa_version":"Published Version","title":"In vitro reconstitution of small GTPase regulation","abstract":[{"text":"Small GTPases play essential roles in the organization of eukaryotic cells.

Here, we show that epigenetic characteristics of closed chromatin, such as DNA methylation, do not influence the binding of p53 across the genome. Instead, the ability of p53 to open chromatin and activate its target genes is locally restricted by its cofactor Trim24. Trim24 binds to both p53 and unmethylated histone 3 lysine 4 (H3K4), thereby preferentially localizing to those p53 sites that reside in closed chromatin, whereas it is deterred from accessible chromatin by H3K4 methylation. The presence of Trim24 increases cell viability upon stress and enables p53 to affect gene expression as a function of the local chromatin state. These findings link H3K4 methylation to p53 function and illustrate how specificity in chromatin can be achieved, not by TF-intrinsic sensitivity to histone modifications, but by employing chromatin-sensitive cofactors that locally modulate TF function."}],"pmid":1,"publication_status":"published","oa_version":"Published Version","title":"Readout of histone methylation by Trim24 locally restricts chromatin opening by p53","page":"948-957","main_file_link":[{"url":"https://doi.org/10.1038/s41594-023-01021-8","open_access":"1"}],"quality_controlled":"1"},{"month":"02","corr_author":"1","publisher":"Institute of Science and Technology Austria","day":"02","degree_awarded":"PhD","keyword":["cryo-EM","cryo-ET","FIB milling","method development","FIBSEM","extracellular matrix","ECM","cell-derived matrices","CDMs","cell culture","high pressure freezing","HPF","structural biology","tomography","collagen"],"year":"2023","type":"dissertation","project":[{"_id":"eba3b5f6-77a9-11ec-83b8-cf0905748aa3","name":"Integrated visual proteomics of reciprocal cell-extracellular matrix interactions"},{"name":"NÃ-Fonds Preis fÃ¼r die Jungforscherin des Jahres am IST Austria","_id":"059B463C-7A3F-11EA-A408-12923DDC885E"}],"status":"public","has_accepted_license":"1","department":[{"_id":"GradSch"},{"_id":"FlSc"}],"article_processing_charge":"No","language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"8586","relation":"part_of_dissertation"}]},"file":[{"access_level":"open_access","creator":"bzens","date_created":"2023-02-07T13:07:38Z","file_name":"PhDThesis_BettinaZens_2023_final.pdf","file_id":"12527","checksum":"069d87f025e0799bf9e3c375664264f2","relation":"main_file","embargo":"2024-02-07","file_size":23082464,"date_updated":"2024-02-08T23:30:04Z","content_type":"application/pdf"},{"embargo_to":"open_access","checksum":"8c66ed203495d6e078ed1002a866520c","date_created":"2023-02-07T13:09:05Z","file_id":"12528","file_name":"PhDThesis_BettinaZens_2023_final.docx","access_level":"closed","creator":"bzens","relation":"source_file","date_updated":"2024-02-08T23:30:04Z","file_size":106169509,"content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document"}],"date_updated":"2026-04-07T13:49:23Z","ddc":["570"],"OA_place":"publisher","_id":"12491","doi":"10.15479/at:ista:12491","date_created":"2023-02-02T14:50:20Z","author":[{"id":"45FD126C-F248-11E8-B48F-1D18A9856A87","full_name":"Zens, Bettina","last_name":"Zens","orcid":"0000-0002-9561-1239","first_name":"Bettina"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","supervisor":[{"orcid":"0000-0003-4790-8078","last_name":"Schur","first_name":"Florian KM","id":"48AD8942-F248-11E8-B48F-1D18A9856A87","full_name":"Schur, Florian KM"}],"citation":{"apa":"Zens, B.

It provides structural scaffolding for the cells embedded within it and is essential in regulating numerous physiological processes, including cell migration and proliferation, wound healing, and stem cell fate. \r\nDespite extensive study, detailed structural knowledge of ECM components in physiologically relevant conditions is still rudimentary. This is due to methodological limitations in specimen preparation protocols which are incompatible with keeping large samples, such as the ECM, in their native state for subsequent imaging. Conventional electron microscopy (EM) techniques rely on fixation, dehydration, contrasting, and sectioning. This results in the alteration of a highly hydrated environment and the potential introduction of artifacts. Other structural biology techniques, such as nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography, allow high-resolution analysis of protein structures but only work on homogenous and purified samples, hence lacking contextual information. Currently, no approach exists for the ultrastructural and structural study of extracellular components under native conditions in a physiological, 3D environment. \r\nIn this thesis, I have developed a workflow that allows for the ultrastructural analysis of the ECM in near-native conditions at molecular resolution. The developments I introduced include implementing a novel specimen preparation workflow for cell-derived matrices (CDMs) to render them compatible with ion-beam milling and subsequent high-resolution cryo-electron tomography (ET). \r\nTo this end, I have established protocols to generate CDMs grown over several weeks on EM grids that are compatible with downstream cryo-EM sample preparation and imaging techniques. Characterization of these ECMs confirmed that they contain essential ECM components such as collagen I, collagen VI, and fibronectin I in high abundance and hence represent a bona fide biologically-relevant sample. I successfully optimized vitrification of these specimens by testing various vitrification techniques and cryoprotectants. \r\nIn order to obtain high-resolution molecular insights into the ultrastructure and organization of CDMs, I established cryo-focused ion beam scanning electron microscopy (FIBSEM) on these challenging and complex specimens. I explored different approaches for the creation of thin cryo-lamellae by FIB milling and succeeded in optimizing the cryo-lift-out technique, resulting in high-quality lamellae of approximately 200 nm thickness. \r\nHigh-resolution Cryo-ET of these lamellae revealed for the first time the architecture of native CDM in the context of matrix-secreting cells. This allowed for the in situ visualization of fibrillar matrix proteins such as collagen, laying the foundation for future structural and ultrastructural characterization of these proteins in their near-native environment. \r\nIn summary, in this thesis, I present a novel workflow that combines state-of-the-art cryo-EM specimen preparation and imaging technologies to permit characterization of the ECM, an important tissue component in higher organisms. This innovative and highly versatile workflow will enable addressing far-reaching questions on ECM architecture, composition, and reciprocal ECM-cell interactions."}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"LifeSc"},{"_id":"Bio"}],"oa_version":"Published Version","title":"Ultrastructural characterization of natively preserved extracellular matrix by cryo-electron tomography","publication_status":"published"},{"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_published":"2022-10-01T00:00:00Z","oa":1,"citation":{"ama":"Gerle C, Kishikawa J, Yamaguchi T, et al.

We found that methylation of G2922 is needed for assembly and efficient nuclear export of the large subunit.

However, aggregation of apoA‐I single point mutants can lead to hereditary amyloid pathology. Although several studies have tackled the biophysical and structural consequences introduced by these mutations, there is little information addressing the relationship between the evolutionary and structural features that contribute to the amyloid behavior of apoA‐I. We combined evolutionary studies, in silico mutagenesis and molecular dynamics (MD) simulations to provide a comprehensive analysis of the conservation and pathogenic role of the aggregation‐prone regions (APRs) present in apoA‐I. Sequence analysis demonstrated that among the four amyloidogenic regions described for human apoA‐I, only two (APR1 and APR4) are evolutionary conserved across different species of Sarcopterygii. Moreover, stability analysis carried out with the FoldX engine showed that APR1 contributes to the marginal stability of apoA‐I. Structural properties of full‐length apoA‐I models suggest that aggregation is avoided by placing APRs into highly packed and rigid portions of its native fold. Compared to silent variants extracted from the gnomAD database, the thermodynamic and pathogenic impact of amyloid mutations showed evidence of a higher destabilizing effect. MD simulations of the amyloid variant G26R evidenced the partial unfolding of the alpha‐helix bundle with the concomitant exposure of APR1 to the solvent, suggesting an insight into the early steps involved in its aggregation. Our findings highlight APR1 as a relevant component for apoA‐I structural integrity and emphasize a destabilizing effect of amyloid variants that leads to the exposure of this region.","lang":"eng"}],"publication_status":"published","title":"Evolutionary and structural constraints influencing apolipoprotein A‐I amyloid behavior","oa_version":"Preprint","date_created":"2024-04-03T07:49:53Z","author":[{"last_name":"Gisonno","first_name":"Romina A.","full_name":"Gisonno, Romina A."},{"last_name":"Masson","orcid":"0000-0002-2634-6283","first_name":"Tomas","id":"93ac43e8-8599-11eb-9b86-f6efb0a4c207","full_name":"Masson, Tomas"},{"first_name":"Nahuel A.","last_name":"Ramella","full_name":"Ramella, Nahuel A."},{"full_name":"Barrera, Exequiel E.","last_name":"Barrera","first_name":"Exequiel E."},{"full_name":"Romanowski, Víctor","first_name":"Víctor","last_name":"Romanowski"},{"full_name":"Tricerri, M.

Here, we assess the performance of recently introduced hardware for cryo-electron tomography (cryo-ET) and subtomogram averaging (STA), an increasingly popular structural determination method for complex 3D specimens. We acquired cryo-ET datasets of EIAV virus-like particles (VLPs) on two contemporary cryo-EM systems equipped with different energy filters and direct electron detectors (DED), specifically a Krios G4, equipped with a cold field emission gun (CFEG), Thermo Fisher Scientific Selectris X energy filter, and a Falcon 4 DED; and a Krios G3i, with a Schottky field emission gun (XFEG), a Gatan Bioquantum energy filter, and a K3 DED. We performed constrained cross-correlation-based STA on equally sized datasets acquired on the respective systems. The resulting EIAV CA hexamer reconstructions show that both systems perform comparably in the 4–6 Å resolution range based on Fourier-Shell correlation (FSC). In addition, by employing a recently introduced multiparticle refinement approach, we obtained a reconstruction of the EIAV CA hexamer at 2.9 Å. Our results demonstrate the potential of the new generation of energy filters and DEDs for STA, and the effects of using different processing pipelines on their STA outcomes.","lang":"eng"}],"publication_status":"published","title":"Exploring high-resolution cryo-ET and subtomogram averaging capabilities of contemporary DEDs","oa_version":"Published Version","quality_controlled":"1","file_date_updated":"2022-08-02T11:07:58Z","acknowledgement":"This work was funded by the Austrian Science Fund (FWF) grant P31445 to F.K.M.S and the National Institute of Allergy and Infectious Diseases under awards R01AI147890 to R.A.D.

This is particularly true for dynamic extra- and intracellular filamentous assemblies, playing a role in cell motility, cell integrity, cytokinesis, tissue formation and maintenance. For example, genetic manipulation or modulation of actin regulatory proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural architecture of actin filament-rich cell peripheral structures, such as lamellipodia or filopodia. However, the observed ultrastructural effects often remain subtle and require sufficiently large datasets for appropriate quantitative analysis. The acquisition of such large datasets has been enabled by recent advances in high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates the development of complementary approaches to maximize the extraction of relevant biological information. We have developed a computational toolbox for the semi-automatic quantification of segmented and vectorized filamentous networks from pre-processed cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple experimental conditions. GUI-based components simplify the processing of data and allow users to obtain a large number of ultrastructural parameters describing filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing cryo-ET data of untreated and chemically perturbed branched actin filament networks and that of parallel actin filament arrays. In principle, the computational toolbox presented here is applicable for data analysis comprising any type of filaments in regular (i.e. parallel) or random arrangement. We show that it can ease the identification of key differences between experimental groups and facilitate the in-depth analysis of ultrastructural data in a time-efficient manner."}],"publication_status":"published","title":"Computational toolbox for ultrastructural quantitative analysis of filament networks in cryo-ET data","oa_version":"Published Version","author":[{"id":"38C393BE-F248-11E8-B48F-1D18A9856A87","full_name":"Dimchev, Georgi A","orcid":"0000-0001-8370-6161","last_name":"Dimchev","first_name":"Georgi A"},{"full_name":"Amiri, Behnam","last_name":"Amiri","first_name":"Behnam"},{"full_name":"Fäßler, Florian","id":"404F5528-F248-11E8-B48F-1D18A9856A87","first_name":"Florian","last_name":"Fäßler","orcid":"0000-0001-7149-769X"},{"last_name":"Falcke","first_name":"Martin","full_name":"Falcke, Martin"},{"full_name":"Schur, Florian KM","id":"48AD8942-F248-11E8-B48F-1D18A9856A87","first_name":"Florian KM","orcid":"0000-0003-4790-8078","last_name":"Schur"}],"date_created":"2021-11-15T12:21:42Z","doi":"10.1016/j.jsb.2021.107808","_id":"10290","scopus_import":"1","oa":1,"date_published":"2021-11-03T00:00:00Z","citation":{"mla":"Dimchev, Georgi A., et al. “Computational Toolbox for Ultrastructural Quantitative Analysis of Filament Networks in Cryo-ET Data.” <i>Journal of Structural Biology</i>, vol. 213, no. 4, 107808, Elsevier , 2021, doi:<a href=\"https://doi.org/10.1016/j.jsb.2021.107808\">10.1016/j.jsb.2021.107808</a>.","chicago":"Dimchev, Georgi A, Behnam Amiri, Florian Fäßler, Martin Falcke, and Florian KM Schur. “Computational Toolbox for Ultrastructural Quantitative Analysis of Filament Networks in Cryo-ET Data.” <i>Journal of Structural Biology</i>.

To understand this phenomenon at the molecular level, we present the first four crystal structures of heterodimeric septin complexes. We describe in detail the two distinct types of G-interface present within the octameric particles, which must polymerize to form filaments. These are formed between SEPT2 and SEPT6 and between SEPT7 and SEPT3, and their description permits an understanding of the structural basis for the selectivity necessary for correct filament assembly. By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's postulate, which predicts the exchangeability of septins from within a subgroup. Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent conformational change, have been repurposed in septins to play a fundamental role in molecular recognition. Specifically, it is switch I which holds the key to discriminating between the two different G-interfaces. Moreover, residues which are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing that the correct interfaces are formed.","lang":"eng"}],"pmid":1,"quality_controlled":"1","page":"5784-5801","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.jmb.2020.09.001"}],"type":"journal_article","year":"2020","keyword":["Molecular Biology","Structural Biology"],"day":"02","issue":"21","publisher":"Elsevier","month":"10","date_updated":"2024-02-28T12:37:54Z","language":[{"iso":"eng"}],"article_processing_charge":"No","department":[{"_id":"MaLo"}],"publication":"Journal of Molecular Biology","external_id":{"pmid":["32910969"]},"status":"public"},{"quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1186/s12915-019-0733-6"}],"publication_status":"published","DOAJ_listed":"1","title":"The mitochondrial carrier pathway transports non-canonical substrates with an odd number of transmembrane segments","oa_version":"Published Version","abstract":[{"lang":"eng","text":"Background: The mitochondrial pyruvate carrier (MPC) plays a central role in energy metabolism by transporting pyruvate across the inner mitochondrial membrane. Its heterodimeric composition and homology to SWEET and semiSWEET transporters set the MPC apart from the canonical mitochondrial carrier family (named MCF or SLC25). The import of the canonical carriers is mediated by the carrier translocase of the inner membrane (TIM22) pathway and is dependent on their structure, which features an even number of transmembrane segments and both termini in the intermembrane space. The import pathway of MPC proteins has not been elucidated. The odd number of transmembrane segments and positioning of the N-terminus in the matrix argues against an import via the TIM22 carrier pathway but favors an import via the flexible presequence pathway.\r\nResults: Here, we systematically analyzed the import pathways of Mpc2 and Mpc3 and report that, contrary to an expected import via the flexible presequence pathway, yeast MPC proteins with an odd number of transmembrane segments and matrix-exposed N-terminus are imported by the carrier pathway, using the receptor Tom70, small TIM chaperones, and the TIM22 complex. The TIM9·10 complex chaperones MPC proteins through the mitochondrial intermembrane space using conserved hydrophobic motifs that are also required for the interaction with canonical carrier proteins.\r\nConclusions: The carrier pathway can import paired and non-paired transmembrane helices and translocate N-termini to either side of the mitochondrial inner membrane, revealing an unexpected versatility of the mitochondrial import pathway for non-cleavable inner membrane proteins."}],"pmid":1,"citation":{"apa":"Rampelt, H., Sucec, I., Bersch, B., Horten, P., Perschil, I., Martinou, J.-C., … Pfanner, N.

Minimal coarse-grained models, in which a whole macromolecule is represented by a small number of particles, can be of great value in identifying the main driving forces behind self-organisation in cell biology. Such models can incorporate data from both molecular and continuum scales, and their results can be directly compared to experiments. Here we review the state of the art of models for studying the formation and biological function of macromolecular assemblies in living organisms. We outline the key ingredients of each model and their main findings.
