Chromatin remodeling and initiation of DNA replication
Frontiers in Bioscience, 2001While much has been learned in recent years about the process of chromatin remodeling and its role in activation of transcription, relatively little has been reported on the role of chromatin remodeling in DNA replication. However, it is well established that transcription factors and chromatin structure play an important role in replication origin ...

The complex for replication initiation ofEscherichia coli
Chromosoma, 1992We probed the complex between oriC and DnaA protein using two types of mutants in oriC. Base changes in the DnaA binding sites, DnaA boxes, had little effect on origin function. Mutations which change the distance between DnaA boxes R3 and R4, on the other hand, inactivated oriC unless the mutation deleted or inserted one complete helical turn. Origins

Initiation of Chromosomal Replication
2014The complex process of bacterial chromosomal replication can be divided into several stages: initiation, priming of chain starts, chain elongation, and termination. Since much of what is known about the initiation of bacterial chromosomal replication comes from studies of Escherichia coli, this chapter concentrates on initiation in that organism.

Initiation of eukaryotic DNA replication in vitro
BioEssays, 1988AbstractRecent advances in our understanding of the mechanism and regulation of eukaryotic DNA replication have been expedited by the use of cell‐free systems capable of initiation of DNA replication. The system capable of replicating plasmid DNAs containing the SV40 origin of DNA replication in vitro is a paradigm for studies on the replication of ...

“Replisome”-controlled initiation of DNA replication
Journal of Theoretical Biology, 1971Abstract A model is presented for initiation of DNA replication according to which a membrane-bound structure, the “replisome”, is brought to maturity on a definite region of the bacterial chromosome. Maturation of replisomes is assumed to be a recurrent process the start and the end of which is marked by initiation of DNA replication.

Initiation of DNA replication in yeast chromosomes
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1987Abstract A family of DNA fragments from the yeast genome has properties that suggest that chromosome replication starts at specific DNA sequences. These elements (autonomously replicating sequences: ARS) have a bipartite structure: a small (less than 20 base pairs) AT-rich region essential for function, flanked by larger regions ...

Initiation of DNA replication in eukaryotic chromosomes
Journal of Cellular Biochemistry, 1998Our understanding of the process by which eukaryotes regulate initiation of DNA replication has made remarkable advances in the past few years, thanks in large part to the explosion of genetic and biochemical information on the budding yeast, Saccharomyces cerevisiae.
