Isolation of Yeast DNA Replication Mutants in Permeabilized Cells [PDF]
A random population of temperature-sensitive mutants was screened by assaying for defects in DNA synthesis in a permeabilized yeast DNA replication system. Twenty mutants defective in in vitro DNA synthesis have been isolated.

Homologous Recombination: To Fork and Beyond [PDF]
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair ...

This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

RAD51 restricts DNA over-replication from re-activated origins
Eukaryotic cells rely on several mechanisms to ensure that the genome is duplicated precisely once in each cell division cycle, preventing DNA over-replication and genomic instability.

Cdt1 stabilizes an open MCM ring for helicase loading
The loading and activation of the Mcm2-7 replicative helicase couples cell cycle progression to DNA replication. Here the authors use X-ray crystallography and single-particle electron microscopy to demonstrate how Ctd1 functions to promote MCM loading ...

In this review, we will summarize new approaches to the study of DNA replication in yeast made possible by recombinant DNA technology, and in particular, survey results obtained with in vitro replication systems. Other recent reviews that summarize previous yeast replication studies are those of Fangman and Zakian and Petes.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Testing Quantum Dynamics in Genetic Information Processing [PDF]
Does quantum dynamics play a role in DNA replication? What type of tests would reveal that? Some statistical checks that distinguish classical and quantum dynamics in DNA replication are proposed.Comment: 4 pages, latex.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

PolySUMOylation of PCNA and Rad52 restricts centromeric recombination in fission yeast
SUMOylation, a conserved post-translational modification in eukaryotes, regulates protein function, localization, and stability. However, the role of SUMO chains in genome maintenance is still emerging.
