text: Coordinated conformational transitions in oligomeric enzymatic complexes modulate
function in response to substrates and play a crucial role in enzyme inhibition
and activation. Caseinolytic protease (ClpP) is a tetradecameric complex, which
has emerged as a drug target against multiple pathogenic bacteria. Activation
of different ClpPs by inhibitors has been independently reported from drug development
efforts, but no rationale for inhibitor-induced activation has been hitherto proposed.
Using an integrated approach that includes x-ray crystallography, solid- and solution-state
nuclear magnetic resonance, molecular dynamics simulations, and isothermal titration
calorimetry, we show that the proteasome inhibitor bortezomib binds to the ClpP
active-site serine, mimicking a peptide substrate, and induces a concerted allosteric
activation of the complex. The bortezomib-activated conformation also exhibits
a higher affinity for its cognate unfoldase ClpX. We propose a universal allosteric
mechanism, where substrate binding to a single subunit locks ClpP into an active
conformation optimized for chaperone association and protein processive degradation.

text: Aromatic residues are located at structurally important sites of many proteins.
Probing their interactions and dynamics can provide important functional insight
but is challenging in large proteins. Here, we introduce approaches to characterize
dynamics of phenylalanine residues using 1H-detected fast magic-angle spinning
(MAS) NMR combined with a tailored isotope-labeling scheme. Our approach yields
isolated two-spin systems that are ideally suited for artefact-free dynamics measurements,
and allows probing motions effectively without molecular-weight limitations. The
application to the TET2 enzyme assembly of ~0.5 MDa size, the currently largest
protein assigned by MAS NMR, provides insights into motions occurring on a wide
range of time scales (ps-ms). We quantitatively probe ring flip motions, and show
the temperature dependence by MAS NMR measurements down to 100 K. Interestingly,
favorable line widths are observed down to 100 K, with potential implications
for DNP NMR. Furthermore, we report the first 13C R1ρ MAS NMR relaxation-dispersion
measurements and detect structural excursions occurring on a microsecond time
scale in the entry pore to the catalytic chamber and at a trimer interface that
was proposed as exit pore. We show that the labeling scheme with deuteration at
ca. 50 kHz MAS provides superior resolution compared to 100 kHz MAS experiments
with protonated, uniformly 13C-labeled samples.

text: The bacterial cell wall is composed of the peptidoglycan (PG), a large polymer
that maintains the integrity of the bacterial cell. Due to its multi-gigadalton
size, heterogeneity, and dynamics, atomic-resolution studies are inherently complex.
Solid-state NMR is an important technique to gain insight into its structure,
dynamics and interactions. Here, we explore the possibilities to study the PG
with ultra-fast (100 kHz) magic-angle spinning NMR. We demonstrate that highly
resolved spectra can be obtained, and show strategies to obtain site-specific
resonance assignments and distance information. We also explore the use of proton-proton
correlation experiments, thus opening the way for NMR studies of intact cell walls
without the need for isotope labeling.

text: 'Studying protein dynamics on microsecond‐to‐millisecond (μs‐ms) time scales
can provide important insight into protein function. In magic‐angle‐spinning (MAS)
NMR, μs dynamics can be visualized by R1p rotating‐frame relaxation dispersion
experiments in different regimes of radio‐frequency field strengths: at low RF
field strength, isotropic‐chemical‐shift fluctuation leads to “Bloch‐McConnell‐type”
relaxation dispersion, while when the RF field approaches rotary resonance conditions
bond angle fluctuations manifest as increased R1p rate constants (“Near‐Rotary‐Resonance
Relaxation Dispersion”, NERRD). Here we explore the joint analysis of both regimes
to gain comprehensive insight into motion in terms of geometric amplitudes, chemical‐shift
changes, populations and exchange kinetics. We use a numerical simulation procedure
to illustrate these effects and the potential of extracting exchange parameters,
and apply the methodology to the study of a previously described conformational
exchange process in microcrystalline ubiquitin.'

text: Microsecond to millisecond timescale backbone dynamics of the amyloid core
residues in Y145Stop human prion protein (PrP) fibrils were investigated by using
15N rotating frame (R1ρ) relaxation dispersion solid‐state nuclear magnetic resonance
spectroscopy over a wide range of spin‐lock fields. Numerical simulations enabled
the experimental relaxation dispersion profiles for most of the fibril core residues
to be modelled by using a two‐state exchange process with a common exchange rate
of 1000 s−1, corresponding to protein backbone motion on the timescale of 1 ms,
and an excited‐state population of 2 %. We also found that the relaxation dispersion
profiles for several amino acids positioned near the edges of the most structured
regions of the amyloid core were better modelled by assuming somewhat higher excited‐state
populations (∼5–15 %) and faster exchange rate constants, corresponding to protein
backbone motions on the timescale of ∼100–300 μs. The slow backbone dynamics of
the core residues were evaluated in the context of the structural model of human
Y145Stop PrP amyloid.

text: NMR relaxation dispersion methods provide a holistic way to observe microsecond
time-scale protein backbone motion both in solution and in the solid state. Different
nuclei (1H and 15N) and different relaxation dispersion techniques (Bloch–McConnell
and near-rotary-resonance) give complementary information about the amplitudes
and time scales of the conformational dynamics and provide comprehensive insights
into the mechanistic details of the structural rearrangements. In this paper,
we exemplify the benefits of the combination of various solution- and solid-state
relaxation dispersion methods on a microcrystalline protein (α-spectrin SH3 domain),
for which we are able to identify and model the functionally relevant conformational
rearrangements around the ligand recognition loop occurring on multiple microsecond
time scales. The observed loop motions suggest that the SH3 domain exists in a
binding-competent conformation in dynamic equilibrium with a sterically impaired
ground-state conformation both in solution and in crystalline form. This inherent
plasticity between the interconverting macrostates is compatible with a conformational-preselection
model and provides new insights into the recognition mechanisms of SH3 domains.

text: 'We consider billiards obtained by removing three strictly convex obstacles
satisfying the non-eclipse condition on the plane. The restriction of the dynamics
to the set of non-escaping orbits is conjugated to a subshift on three symbols
that provides a natural labeling of all periodic orbits. We study the following
inverse problem: does the Marked Length Spectrum (i.e., the set of lengths of
periodic orbits together with their labeling), determine the geometry of the billiard
table? We show that from the Marked Length Spectrum it is possible to recover
the curvature at periodic points of period two, as well as the Lyapunov exponent
of each periodic orbit.'

text: Inhibiting the histone H3–ASF1 (anti‐silencing function 1) protein–protein
interaction (PPI) represents a potential approach for treating numerous cancers.
As an α‐helix‐mediated PPI, constraining the key histone H3 helix (residues 118–135)
is a strategy through which chemical probes might be elaborated to test this hypothesis.
In this work, variant H3118–135 peptides bearing pentenylglycine residues at the
i and i+4 positions were constrained by olefin metathesis. Biophysical analyses
revealed that promotion of a bioactive helical conformation depends on the position
at which the constraint is introduced, but that the potency of binding towards
ASF1 is unaffected by the constraint and instead that enthalpy–entropy compensation
occurs.

text: Anti-silencing function 1 (ASF1) is a conserved H3-H4 histone chaperone involved
in histone dynamics during replication, transcription, and DNA repair. Overexpressed
in proliferating tissues including many tumors, ASF1 has emerged as a promising
therapeutic target. Here, we combine structural, computational, and biochemical
approaches to design peptides that inhibit the ASF1-histone interaction. Starting
from the structure of the human ASF1-histone complex, we developed a rational
design strategy combining epitope tethering and optimization of interface contacts
to identify a potent peptide inhibitor with a dissociation constant of 3 nM. When
introduced into cultured cells, the inhibitors impair cell proliferation, perturb
cell-cycle progression, and reduce cell migration and invasion in a manner commensurate
with their affinity for ASF1. Finally, we find that direct injection of the most
potent ASF1 peptide inhibitor in mouse allografts reduces tumor growth. Our results
open new avenues to use ASF1 inhibitors as promising leads for cancer therapy.

text: Molecular motors are essential to the living, generating fluctuations that
boost transport and assist assembly. Active colloids, that consume energy to move,
hold similar potential for man-made materials controlled by forces generated from
within. Yet, their use as a powerhouse in materials science lacks. Here we show
a massive acceleration of the annealing of a monolayer of passive beads by moderate
addition of self-propelled microparticles. We rationalize our observations with
a model of collisions that drive active fluctuations and activate the annealing.
The experiment is quantitatively compared with Brownian dynamic simulations that
further unveil a dynamical transition in the mechanism of annealing. Active dopants
travel uniformly in the system or co-localize at the grain boundaries as a result
of the persistence of their motion. Our findings uncover the potential of internal
activity to control materials and lay the groundwork for the rise of materials
science beyond equilibrium.

text: 'Bending-active structures are able to efficiently produce complex curved
shapes starting from flat panels. The desired deformation of the panels derives
from the proper selection of their elastic properties. Optimized panels, called
FlexMaps, are designed such that, once they are bent and assembled, the resulting
static equilibrium configuration matches a desired input 3D shape. The FlexMaps
elastic properties are controlled by locally varying spiraling geometric mesostructures,
which are optimized in size and shape to match the global curvature (i.e., bending
requests) of the target shape. The design pipeline starts from a quad mesh representing
the input 3D shape, which defines the edge size and the total amount of spirals:
every quad will embed one spiral. Then, an optimization algorithm tunes the geometry
of the spirals by using a simplified pre-computed rod model. This rod model is
derived from a non-linear regression algorithm which approximates the non-linear
behavior of solid FEM spiral models subject to hundreds of load combinations.
This innovative pipeline has been applied to the project of a lightweight plywood
pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted arc
that fits a bounding box of 3.90x3.96x3.25 meters.'

text: Epigenetic reprogramming is required for proper regulation of gene expression
in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for
seed viability, pollen function, and successful reproduction. The DEMETER (DME)
DNA glycosylase initiates localized DNA demethylation in vegetative and central
cells, so-called companion cells that are adjacent to sperm and egg gametes, respectively.
In rice, the central cell genome displays local DNA hypomethylation, suggesting
that active DNA demethylation also occurs in rice; however, the enzyme responsible
for this process is unknown. One candidate is the rice REPRESSOR OF SILENCING
1a (ROS1a) gene, which is related to DME and is essential for rice seed viability
and pollen function. Here, we report genome-wide analyses of DNA methylation in
wild-type and ros1a mutant sperm and vegetative cells. We find that the rice vegetative
cell genome is locally hypomethylated compared with sperm by a process that requires
ROS1a activity. We show that many ROS1a target sequences in the vegetative cell
are hypomethylated in the rice central cell, suggesting that ROS1a also demethylates
the central cell genome. Similar to Arabidopsis, we show that sperm non-CG methylation
is indirectly promoted by DNA demethylation in the vegetative cell. These results
reveal that DNA glycosylase-mediated DNA demethylation processes are conserved
in Arabidopsis and rice, plant species that diverged 150 million years ago. Finally,
although global non-CG methylation levels of sperm and egg differ, the maternal
and paternal embryo genomes show similar non-CG methylation levels, suggesting
that rice gamete genomes undergo dynamic DNA methylation reprogramming after cell
fusion.

text: "Background\r\nDNA methylation of active genes, also known as gene body methylation,
is found in many animal and plant genomes. Despite this, the transcriptional and
developmental role of such methylation remains poorly understood. Here, we explore
the dynamic range of DNA methylation in honey bee, a model organism for gene body
methylation.\r\n\r\nResults\r\nOur data show that CG methylation in gene bodies
globally fluctuates during honey bee development. However, these changes cause
no gene expression alterations. Intriguingly, despite the global alterations,
tissue-specific CG methylation patterns of complete genes or exons are rare, implying
robust maintenance of genic methylation during development. Additionally, we show
that CG methylation maintenance fluctuates in somatic cells, while reaching maximum
fidelity in sperm cells. Finally, unlike universally present CG methylation, we
discovered non-CG methylation specifically in bee heads that resembles such methylation
in mammalian brain tissue.\r\n\r\nConclusions\r\nBased on these results, we propose
that gene body CG methylation can oscillate during development if it is kept to
a level adequate to preserve function. Additionally, our data suggest that heightened
non-CG methylation is a conserved regulator of animal nervous systems."

text: An r-cut of a k-uniform hypergraph H is a partition of the vertex set of H
into r parts and the size of the cut is the number of edges which have a vertex
in each part. A classical result of Edwards says that every m-edge graph has a
2-cut of size m/2+Ω)(m−−√) and this is best possible. That is, there exist cuts
which exceed the expected size of a random cut by some multiple of the standard
deviation. We study analogues of this and related results in hypergraphs. First,
we observe that similarly to graphs, every m-edge k-uniform hypergraph has an
r-cut whose size is Ω(m−−√) larger than the expected size of a random r-cut. Moreover,
in the case where k = 3 and r = 2 this bound is best possible and is attained
by Steiner triple systems. Surprisingly, for all other cases (that is, if k ≥
4 or r ≥ 3), we show that every m-edge k-uniform hypergraph has an r-cut whose
size is Ω(m5/9) larger than the expected size of a random r-cut. This is a significant
difference in behaviour, since the amount by which the size of the largest cut
exceeds the expected size of a random cut is now considerably larger than the
standard deviation.

text: An n-vertex graph is called C-Ramsey if it has no clique or independent set
of size C log n. All known constructions of Ramsey graphs involve randomness in
an essential way, and there is an ongoing line of research towards showing that
in fact all Ramsey graphs must obey certain “richness” properties characteristic
of random graphs. More than 25 years ago, Erdős, Faudree and Sós conjectured that
in any C-Ramsey graph there are Ω(n^5/2) induced subgraphs, no pair of which have
the same numbers of vertices and edges. Improving on earlier results of Alon,
Balogh, Kostochka and Samotij, in this paper we prove this conjecture.
