Structure-function studies of DNA polymerase lambda

DNA Repair (Amst). 2005 Dec 8;4(12):1358-67. doi: 10.1016/j.dnarep.2005.09.001. Epub 2005 Oct 4.

Abstract

DNA polymerase lambda is a member of the X family of polymerases that is implicated in non-homologous end-joining of double-strand breaks in DNA and in base excision repair of DNA damage. To better understand the roles of DNA polymerase lambda in these repair pathways, here we review its structure and biochemical properties, with emphasis on its gap-filling polymerization activity, its dRP lyase activity and its unusual DNA synthetic (in)fidelity.
