Metazoan DNA replication origins [PDF]
DNA replication starts with the opening of DNA at sites called DNA replication origins. From the single sequence-specific DNA replication origin of the small Escherichia coli genome, up to thousands of origins that are necessary to replicate the large human genome, strict sequence specificity has been lost.

Cytomegalovirus replicon-based regulation of gene expression in vitro and in vivo [PDF]
There is increasing evidence for a connection between DNA replication and the expression of adjacent genes. Therefore, this study addressed the question of whether a herpesvirus origin of replication can be used to activate or increase the expression of ...

Dynamic distribution of SeqA protein across the chromosome of Escherichia coli K-12 [PDF]
The bacterial SeqA protein binds to hemi-methylated GATC sequences that arise in newly synthesized DNA upon passage of the replication machinery. In Escherichia coli K-12, the single replication origin oriC is a well-characterized target for SeqA, which ...

The elusive determinants of replication origins [PDF]
Despite their central role in maintaining genetic integrity during cell division, there is still considerable uncertainty about how DNA sequences are selected to be replication origins in eukaryotes (DePamphilis, 1999; Gilbert, 2001; Machida et al , 2005). The budding yeast Saccharomyces cerevisiae uses a limited set of efficient origins, each of which

A Dynamic Stochastic Model for DNA Replication Initiation in Early Embryos
Background: Eukaryotic cells seem unable to monitor replication completion during normal S phase, yet must ensure a reliable replication completion time.

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

Mapping of origin of replication in Themococcales [PDF]
Genome replication is a crucial and essential process for the continuity of life.In all organisms it starts at a specific region of the genome known as origin of replication (Ori) site. The number of Ori sites varies in prokaryotes and eukaryotes. Replication starts at a single Ori site in bacteria, but in eukaryotes multiple Ori sites are used for ...

In Escherichia coli, replisome and replication fork assembly is initiated by DnaB helicase loading at the chromosomal origin oriC via its interactions with the DnaA initiator and the DnaC helicase loader.

Comprehensive Analysis of Replication Origins in Saccharomyces cerevisiae Genomes
DNA replication initiates from multiple replication origins (ORIs) in eukaryotes. Discovery and characterization of replication origins are essential for a better understanding of the molecular mechanism of DNA replication. In this study, the features of

Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
