Avoiding chromosome pathology when replication forks collide [PDF]

open access: yes, 2013
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2013 Macmillan Publishers Limited.Chromosome duplication normally initiates through the assembly of replication fork complexes at defined ...

A conserved mechanism for regulating replisome disassembly in eukaryotes

open access: yesNature, 2021
Replisome disassembly is the final step of eukaryotic DNA replication and is triggered by ubiquitylation of the CDC45–MCM–GINS (CMG) replicative helicase1–3.

Bacterial replisomes

open access: yesCurrent Opinion in Structural Biology, 2018
Bacterial replisomes are dynamic multiprotein DNA replication machines that are inherently difficult for structural studies. However, breakthroughs continue to come. The structures of Escherichia coli DNA polymerase III (core)-clamp-DNA subcomplexes solved by single-particle cryo-electron microscopy in both polymerization and proofreading modes and the

Towards a Structural Mechanism for Sister Chromatid Cohesion Establishment at the Eukaryotic Replication Fork

open access: yesBiology, 2021
Cohesion between replicated chromosomes is essential for chromatin dynamics and equal segregation of duplicated genetic material. In the G1 phase, the ring-shaped cohesin complex is loaded onto duplex DNA, enriching at replication start sites, or ...

A link between transcription fidelity and pausing in vivo [PDF]

open access: yes, 2017
Pausing by RNA polymerase is a major mechanism that regulates transcription elongation but can cause conflicts with fellow RNA polymerases and other cellular machineries. Here, we summarize our recent finding that misincorporation could be a major source

The Escherichia coli chromosome moves to the replisome

open access: yesbioRxiv, 2023
The replisome, a large multi-subunit assembly, carries out the process of chromosome replication, connecting the unwrapping of the parental DNA with the creation of new daughter strands.

Replisome Dynamics during Chromosome Duplication [PDF]

open access: yesEcoSal Plus, 2009
This review describes the components of the Escherichia coli replisome and the dynamic process in which they function and interact under normal conditions. It also briefly describes the behavior of the replisome during situations in which normal replication fork movement is disturbed, such as when the replication ...

Sen1 Is Recruited to Replication Forks via Ctf4 and Mrc1 and Promotes Genome Stability

open access: yesCell Reports, 2020
Summary: DNA replication and RNA transcription compete for the same substrate during S phase. Cells have evolved several mechanisms to minimize such conflicts.

MutS regulates access of the error-prone DNA polymerase Pol IV to replication sites: a novel mechanism for maintaining replication fidelity [PDF]

open access: yes, 2016
Translesion DNA polymerases (Pol) function in the bypass of template lesions to relieve stalled replication forks but also display potentially deleterious mutagenic phenotypes that contribute to antibiotic resistance in bacteria and lead to human disease.

Transcription as a Threat to Genome Integrity [PDF]

open access: yes, 2016
Genomes undergo different types of sporadic alterations, including DNA damage, point mutations, and genome rearrangements, that constitute the basis for evolution.
