DNA-dependent DNA polymerases

Curr Protoc Mol Biol. 2008 Oct;Chapter 3:Unit3.5. doi: 10.1002/0471142727.mb0305s84.


This unit presents characteristics and reaction conditions of the DNA-dependent DNA polymerases, including E. coli DNA polymerase I and its Klenow fragment, T4 DNA polymerase, native and modified T7 DNA polymerase, phi29 DNA polymerase, Bst DNA polymerase, and Taq DNA polymerase. The unit also provides overviews of other classes of thermophilic DNA polymerases used in PCR applications (described fully in UNIT 15.1), and the rapidly expanding class of lesion-bypass DNA polymerases that play a role in DNA damage repair.
