3.1.1 Replisome structure and function In E. coli, there are five different DNA polymerases. DNA polymerase III (Pol III) is the chromosomal replicase whereas DNA polymerase I is implicated in RNA primer removal on the lagging-strand. Both of these polymerases can also participate in DNA repair...

高保真Taq酶的保真原理是:高保真Taq酶具有3"到5"核酸外切酶的活性,PCR扩增途中如果产生了错配的碱基,它可以将其切掉,从而保证了扩增的准确性;需要提醒的是由于此酶具有核酸外切酶功能,往往扩增效率低一些,有的还会降解引物,而且产物一般不宜用TA或UA克隆法克隆。 高保真Taq酶的外切活性会导致PCR反应之后不会加尾,所以...

BACKGROUND: Mitochondrial DNA polymerase gamma (POLG1) mutations were associated with levodopa-responsive Parkinsonism. POLG1 gene contains a number of common nonsynonymous SNPs and intronic regulatory SNPs which may have functional consequences. It is of great interest to discover polymorphisms variants ...
Comprehensive studies of DNA polymerase protein levels in cancer remain to be carried out. The inhibition of DNA polymerase activities could be useful as an adjuvant to DNA-damaging therapies, and inhibitors for some polymerases have been found. Pharmacologically effective inhibitors highly specific for...

]. Once loaded, the sliding clamp allows the binding of other polymerase subunits. The crystal structure of a β-clamp was first determined for E. coli in 1992 [5], and after that for five other bacteria so far [6-8]. The structures show that the bacterial sliding clamp is a head-...
DNA polymerase ζ (Polζ) belongs to the same B-family as high-fidelity replicative polymerases, yet is specialized for the extension reaction in translesion DNA synthesis (TLS). Despite its importance in TLS, the structure of Polζ is unknown. We present cryo-EM structures of theSaccharomyces...
