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}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CBF79828.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=EAA61839.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
