Jan 20, 2006 · First, unlike the collision model where the signal is the passive contact of the 3′ end of the previous Okazaki fragment with the lagging strand polymerase, the signaling model is an active mechanism and allows control over the tempo of lagging strand synthesis by, for example, adjusting the cellular clamp or clamp loader concentrations.

Jun 03, 2005 · Bacteriophage T4 initiates origin-dependent replication via an R-loop mechanism in vivo.During in vitro reactions, the phage-encoded gp59 stimulates loading of the replicative helicase, gp41, onto branched intermediates, including origin R-loops. However, although gp59 is essential for recombination-dependent replication from D-loops, it does not appear to be …

Get a QuoteFeb 09, 2015 · Overview of clamp loader mechanism. Clamp loaders are circular heteropentamers with ATP sites situated at subunit interfaces. Three domains in each subunit include the N-terminal AAA+ domains and a C-terminal oligomerization domain referred to as a collar. ATP binding enables binding to the C-face of the clamp, opening it at one interface.

Although most prokaryotes and eukaryotes require ATPase loader for loading helicases to origin DNA, archaea do not have a specific loader for helicase, but instead the initiator protein alone functions as the loader (Barry & Bell 2006). Even in prokaryotes, there is an exception.

Aug 01, 2013 · The same mechanism suggested for the asymmetry of rRNA operons (Section 3.2.2) could operate at the whole genome scale. Indeed, different levels of transcription from leading- and lagging-strand replicated chromosomes could be a mechanism to distinguish between strands . 3.5. Asymmetric segregation of the nucleoid

RecBC cleaves both strands 4-6 bp on the 5'-side of the Chi site. The RecB nuclease arm degrades both strands as it moves towards the Chi site as a member of the RecBCD complex. The nuclease arm of RecB acts as an endonuclease and also serves to load RecA monomers onto the 3'-terminal strand after the Chi site is recognized.
Get a QuoteThe loader protein delivers the helicase on to the melted DNA single strands of the DnaA– ori C nucleoprotein complex at the origin of replication. In vivo, this delivery is associated with the initiator protein, DnaA, whose amino-terminal domain (NTD) is thought to have a role in loading the helicase and helicase loader complex onto the ori C by interacting with helicase, DnaB.

Mainly, ATP binding is required for formation of a clamp loader·clamp·ptDNA complex, and ATP hydrolysis is required for dissociation of the complex to release the clamp·ptDNA product. 22,25-27 More detailed information about the reaction mechanism is available from transient kinetic studies of E. coli and bacteriophage T4 clamp loaders
