Bacteriol. 177:2892-2900(1995). CC -!- FUNCTION: Involved in base excision repair of DNA damaged by oxidation CC or by mutagenic agents. Acts as a DNA glycosylase that recognizes and CC removes damaged bases. Has a preference for oxidized purines, such as CC 7,8-dihydro-8-oxoguanine (8-oxoG). Has AP (apurinic/apyrimidinic) lyase CC activity and introduces nicks in the DNA strand. Cleaves the DNA CC backbone by beta-delta elimination to generate a single-strand break at CC the site of the removed base with both 3'- and 5'-phosphates (By CC similarity). {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Hydrolysis of DNA containing ring-opened 7-methylguanine CC residues, releasing 2,6-diamino-4-hydroxy-5-(N- CC methyl)formamidopyrimidine.; EC=3.2.2.23; 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; CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250}; CC Note=Binds 1 zinc ion per subunit. {ECO:0000250}; CC -!- SUBUNIT: Monomer. {ECO:0000250}. CC -!- SIMILARITY: Belongs to the FPG family. {ECO:0000305}.
