Comparison among DNA polymerases 1, 2 and 3 from …

Three DNA polymerase activities, named 1, 2 and 3 were purified from maize embryo axes and were compared in terms of ion requirements, optimal pH, temperature and KCl for activity, response to specific inhibitors and use of templates. All three enzymes require a divalent cation for activity, but main differences were observed in sensitivity to inhibitors and template usage: while DNA

DNA Polymerase I (E. coli)
DNA Polymerase I (E coli) is a DNA-dependent DNA polymerase with inherent 3´→ 5´ and 5´→ 3´ exonuclease activities (1).The 5´→ 3´ exonuclease activity removes nucleotides ahead of the growing DNA chain, allowing nick-translation. Product Source An E. coli strain that carries an overexpressed copy of the polA gene.

DNA-polymerase
DNA-polymerase voegt basen toe in de 5′ → 3′-richting, en heeft om in gang te komen een primer nodig. Een primer is een kort RNA fragment met een open einde. Primers bestaan uit RNA- en DNA-basen waarvan de eerste twee basen altijd RNA zijn, die gesynthetiseerd zijn door het primase-enzym .

DNA polymerase II
DNA Polymerase II is an 89.9-kDa protein and is a member of the B family of DNA polymerases. It was originally isolated by Thomas Kornberg in 1970, and characterized over the next few years. The in vivo functionality of Pol II is under debate, yet consensus shows that Pol II is primarily involved as a backup enzyme in prokaryotic DNA replication.
