8-oxoguanine DNA glycosylase, N-terminal (IPR012904)

Short name: OGG_N

Overlapping homologous superfamilies


Domain relationships



The presence of 8-oxoguanine residues in DNA can give rise to G-C to T-A transversion mutations. This enzyme is found in archaeal, bacterial and eukaryotic species, and is specifically responsible for the process which leads to the removal of 8-oxoguanine residues. It has DNA glycosylase activity (EC: and DNA lyase activity (EC: [PMID: 10706276]. The region featured in this family is the N-terminal domain, which is organised into a single copy of a TBP-like fold. The domain contributes residues to the 8-oxoguanine binding pocket [PMID: 11902834].
