Replication initiation at the Escherichia coli chromosomal origin

JM Kaguni - Current opinion in chemical biology, 2011 - Elsevier
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 …

Replication initiation in bacteria

S Chodavarapu, JM Kaguni - The Enzymes, 2016 - Elsevier
The initiation of chromosomal DNA replication starts at a replication origin, which in bacteria
is a discrete locus that contains DNA sequence motifs recognized by an initiator protein …
