WebBeta clamp (Beta subunit Homodimer, which forms a ring shaped structure and serves as a sliding clamp) functions as a part of processivity present in DNA polymerase. Bets clamp function is that it holds the DNA polymerase in the position from which it copies or replicates the DNA so that it does not dissociate from it. It is a complex of ... WebDNA polymerase III holoenzyme is the enzyme primarily responsible for replicative DNA synthesis in E. coli. It carries out primer-initiated 5' to 3' polymerization of DNA on a single-stranded DNA template, as well as 3' to 5' exonucleolytic editing of mispaired nucleotides.
