Genetic and physical mapping of DNA replication origins in Haloferax volcanii. [PDF]

PLoS Genetics, 2007
The halophilic archaeon Haloferax volcanii has a multireplicon genome, consisting of a main chromosome, three secondary chromosomes, and a plasmid. Genes for the initiator protein Cdc6/Orc1, which are commonly located adjacent to archaeal origins of DNA ...

Coupling between DNA replication, segregation, and the onset of constriction in Escherichia coli

Cell Reports, 2022
Summary: Escherichia coli cell cycle features two critical cell-cycle checkpoints: initiation of replication and the onset of constriction. While the initiation of DNA replication has been extensively studied, it is less clear what triggers the onset of ...

Coordinate initiation of chromosome and minichromosome replication in Escherichia coli [PDF]

Journal of Bacteriology, 1987
Escherichia coli minichromosomes harboring as little as 327 base pairs of DNA from the chromosomal origin of replication (oriC) were found to replicate in a discrete burst during the division cycle of cells growing with generation times between 25 and 60 min at 37 degrees C. The mean cell age at minichromosome replication coincided with the mean age at

Cloning, expression, and chromosomal localization of the 140-kilodalton subunit of replication factor C from mice and humans [PDF]

, 1994
We have isolated a full-length mouse cDNA encoding a lysine-rich protein of 1,131 amino acids with a calculated molecular mass of 126 kDa. The protein binds in a sequence-unspecific manner to DNA, is localized exclusively in the nucleus, and contains a ...

The DNA replication initiation protein DnaD recognises a specific strand of the Bacillus subtilis chromosome origin [PDF]

, 2023
Genome replication is a fundamental biological activity shared by all organisms. Chromosomal replication proceeds bidirectionally from origins, requiring the loading of two helicases, one for each replisome. However, the molecular mechanisms underpinning

Replication initiation at the Escherichia coli chromosomal origin [PDF]

Current Opinion in Chemical Biology, 2011
To initiate DNA replication, DnaA recognizes and binds to specific sequences within the Escherichia coli chromosomal origin (oriC), and then unwinds a region within oriC. Next, DnaA interacts with DnaB helicase in loading the DnaB-DnaC complex on each separated strand. Primer formation by primase (DnaG) induces the dissociation of DnaC from DnaB, which

Leishmania major chromosomes are replicated from a single high-efficiency locus supplemented by thousands of lower efficiency initiation events

Cell Reports
Summary: DNA replication initiates at genome sites termed origins. Previous origin mapping approaches in the populations of the protozoan parasite Leishmania major were discordant, suggesting either a single origin per chromosome or 200-fold more origins.

Ultrafine anaphase bridges, broken DNA and illegitimate recombination induced by a replication fork barrier [PDF]

, 2011
Most DNA double-strand breaks (DSBs) in S- and G2-phase cells are repaired accurately by Rad51-dependent sister chromatid recombination. However, a minority give rise to gross chromosome rearrangements (GCRs), which can result in disease/death.

Genome-wide analysis reveals extensive functional interaction between DNA replication initiation and transcription in the genome of trypanosoma brucei [PDF]

, 2012
Identification of replication initiation sites, termed origins, is a crucial step in understanding genome transmission in any organism. Transcription of the Trypanosoma brucei genome is highly unusual, with each chromosome comprising a few discrete ...
