DNA replication and transcription generate DNA supercoiling, which can cause topological stress and intertwining of daughter chromatin fibers, posing challenges to the completion of DNA replication and chromosome segregation.

Cells must accurately replicate and segregate their DNA once per cell cycle in order to successfully transmit genetic information. During S phase in the presence of agents that cause replication stress, ATR-dependent checkpoints regulate origin firing ...

Structure and stability of recombinant bovine odorant-binding protein: I. Design and analysis of monomeric mutants [PDF]
Bovine odorant-binding protein (bOBP) differs from other lipocalins by lacking the conserved disulfide bond and for being able to form the domain-swapped dimers.

Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

PARP3 is a sensor of nicked nucleosomes and monoribosylates histone H2BGlu2
Chromosomal single-strand DNA breaks occur frequently and require repair to avoid disease outcomes. Here, the authors show that in bird cells, PARP3 accelerates this repair, and use structural biology and cell biology techniques to reveal details of the ...

Structure and stability of recombinant bovine odorant-binding protein: III. Peculiarities of the wild type bOBP unfolding in crowded milieu [PDF]
Contrary to the majority of the members of the lipocalin family, which are stable monomers with the specific OBP fold (a β-barrel consisting of a 8-stranded anti-parallel β-sheet followed by a short α-helical segment, a ninth β-strand, and a disordered C-

The equivalence ofB-stability andA-stability
It is well known that linear and nonlinear stability concepts are equivalent for linear multistep methods in their one-leg formulation. This result is extended to Runge-Kutta methods. In particular, it is shown here that given an irreducible rational function R(z) whose degrees of numerator and denominator are at most s which has order of approximation

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Molecular basis for DNA repair synthesis on short gaps by mycobacterial Primase-Polymerase C
Mycobacteria Prim-PolC performs short gap synthesis following removal of lesions during excision repair. Here the authors resolve crystal structures of pre- and post-catalytic Prim-PolC complexes bound to gapped DNA substrates to define its mechanism.
