Cellular location and activity of Escherichia coli RecG proteins shed light on the function of its structurally unresolved C-terminus [PDF]

open access: yes, 2014
RecG is a DNA translocase encoded by most species of bacteria. The Escherichia coli protein targets branched DNA substrates and drives the unwinding and rewinding of DNA strands.

Characterization of DnaB–DnaG Interaction in M. tuberculosis Using Small‐Angle X‐ray Scattering‐Based Dissociation Assay

open access: yesChemBioChem, Volume 26, Issue 14, July 18, 2025.
The study characterizes interactions between DnaB helicase and DnaG primase in Mycobacterium tuberculosis using small‐angle X‐ray scattering, surface plasmon resonance, and cross‐linking. The findings reveal that DnaG forms dimers in solution, which are destabilized upon DnaB binding.

The Organisation of Replisomes

open access: yes, 2011
The eukaryotic chromosomal DNA is divided into hundreds to thousands of independent replication segments called replicons. Each replicon is replicated from one replication origin. In the S phase of the cell cycle, individual replicons are gradually activated and subsequently replicated (Edenberg & Huberman, 1975; Hand, 1978).

Chromosome organization shapes replisome dynamics in Caulobacter crescentus

open access: yesNature Communications
DNA replication in bacteria takes place on highly compacted chromosomes, where segregation, transcription, and repair must occur simultaneously. Within this dynamic environment, colocalization of sister replisomes has been observed in many bacterial ...

Coordinated degradation of replisome components ensures genome stability upon replication stress in the absence of the replication fork protection complex.

open access: yesPLoS Genetics, 2013
The stabilization of the replisome complex is essential in order to achieve highly processive DNA replication and preserve genomic integrity. Conversely, it would also be advantageous for the cell to abrogate replisome functions to prevent inappropriate ...

Compact Origins and Where to Find Them: ORC's Guide to Genome‐Wide Licensing

open access: yesBioEssays, Volume 47, Issue 7, July 2025.
Origin licensing is a key requirement for any eukaryotic cell to initiate DNA replication in S‐phase. Here, we review the most recent findings in the orchestrated action of the origin recognition complex (ORC) to sequentially load two MCM2‐7 helicases onto DNA with a focus on origin architecture and sequencing‐based methods.

The Replisome Mediates A-NHEJ Repair of Telomeres Lacking POT1-TPP1 Independently of MRN Function

open access: yesCell Reports, 2019
Summary: Telomeres use shelterin to protect chromosome ends from activating the DNA damage sensor MRE11-RAD50-NBS1 (MRN), repressing ataxia-telangiectasia, mutated (ATM) and ATM and Rad3-related (ATR) dependent DNA damage checkpoint responses.

Modulation of DNA damage tolerance in Escherichia coli recG and ruv strains by mutations affecting PriB, the ribosome and RNA polymerase [PDF]

open access: yes, 2012
RecG is a DNA translocase that helps to maintain genomic integrity. Initial studies suggested a role in promoting recombination, a possibility consistent with synergism between recG and ruv null alleles and reinforced when the protein was shown to unwind

Replisome bypass of a protein-based R-loop block by Pif1

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance The replisome machine that duplicates the DNA genome encounters a variety of blocks to replication, such as DNA bound proteins, R-loops, and DNA lesions.
