Biol. 46:S2-13(2009). CC -!- FUNCTION: Bifunctional DNA N-glycosylase with associated CC apurinic/apyrimidinic (AP) lyase function that catalyzes the first CC step in base excision repair (BER), the primary repair pathway for CC the repair of oxidative DNA damage. The DNA N-glycosylase activity CC releases the damaged DNA base from DNA by cleaving the N- CC glycosidic bond, leaving an AP site. The AP lyase activity cleaves CC the phosphodiester bond 3' to the AP site by a beta-elimination. CC Primarily recognizes and repairs oxidative base damage of CC pyrimidines. {ECO:0000255|HAMAP-Rule:MF_03183}. CC -!- CATALYTIC ACTIVITY: The C-O-P bond 3' to the apurinic or CC apyrimidinic site in DNA is broken by a beta-elimination reaction, CC leaving a 3'-terminal unsaturated sugar and a product with a CC terminal 5'-phosphate. {ECO:0000255|HAMAP-Rule:MF_03183}. CC -!- COFACTOR: CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; CC Evidence={ECO:0000255|HAMAP-Rule:MF_03183}; CC Note=Binds 1 [4Fe-4S] cluster. The cluster does not appear to play CC a role in catalysis, but is probably involved in the proper CC positioning of the enzyme along the DNA strand. CC {ECO:0000255|HAMAP-Rule:MF_03183}; CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|HAMAP-Rule:MF_03183}. CC Mitochondrion {ECO:0000255|HAMAP-Rule:MF_03183}. CC -!- SIMILARITY: Belongs to the Nth/MutY family. {ECO:0000255|HAMAP- CC Rule:MF_03183}.
