General annotation (Comments)

Function

DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate By similarity. HAMAP-Rule MF_00942

Catalytic activity

The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate. HAMAP-Rule MF_00942

Cofactor

Binds 1 4Fe-4S cluster By similarity.

Disruption phenotype

Cells lacking this gene have a 5-fold increased spontaneous mutation frequency. A triple MutS/MutL/nth disruption has a 280-fold increased spontaneous mutation frequency. Ref.4

Sequence similarities

Belongs to the Nth/MutY family.

Contains 1 HhH domain.
