CC   -!- FUNCTION: Involved in base excision repair of DNA damaged by oxidation
CC       or by mutagenic agents. Acts as 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.
CC       {ECO:0000255|HAMAP-Rule:MF_00103}.
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         Evidence={ECO:0000255|HAMAP-Rule:MF_00103};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA
CC         is broken by a beta-elimination reaction, leaving a 3'-terminal
CC         unsaturated sugar and a product with a terminal 5'-phosphate.;
CC         EC=4.2.99.18; Evidence={ECO:0000255|HAMAP-Rule:MF_00103};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00103};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00103};
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00103}.
CC   -!- SIMILARITY: Belongs to the FPG family. {ECO:0000255|HAMAP-
CC       Rule:MF_00103}.
