Biol. 46:S2-13(2009). CC -!- FUNCTION: Bifunctional DNA N-glycosylase with associated CC apurinic/apyrimidinic (AP) lyase function that catalyzes the first step CC in base excision repair (BER), the primary repair pathway for the CC repair of oxidative DNA damage. The DNA N-glycosylase activity releases CC the damaged DNA base from DNA by cleaving the N-glycosidic bond, CC leaving an AP site. The AP lyase activity cleaves the phosphodiester CC bond 3' to the AP site by a beta-elimination. Primarily recognizes and CC repairs oxidative base damage of pyrimidines. {ECO:0000255|HAMAP- CC Rule:MF_03183}. CC -!- CATALYTIC ACTIVITY: CC Reaction=2'-deoxyribonucleotide-(2'-deoxyribose 5'-phosphate)-2'- CC deoxyribonucleotide-DNA = a 3'-end 2'-deoxyribonucleotide-(2,3- CC dehydro-2,3-deoxyribose 5'-phosphate)-DNA + a 5'-end 5'-monophospho- CC 2'-deoxyribonucleoside-DNA + H(+); Xref=Rhea:RHEA:66592, Rhea:RHEA- CC COMP:13180, Rhea:RHEA-COMP:16897, Rhea:RHEA-COMP:17067, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:136412, ChEBI:CHEBI:157695, CC ChEBI:CHEBI:167181; EC=4.2.99.18; Evidence={ECO:0000255|HAMAP- CC 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 a CC role in catalysis, but is probably involved in the proper positioning CC of the enzyme along the DNA strand. {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}.
