CC   -!- FUNCTION: Involved in base excision repair of DNA damaged by
CC       oxidation or by mutagenic agents. Acts as DNA glycosylase that
CC       recognizes and removes damaged bases. Has a preference for
CC       oxidized purines, such as 7,8-dihydro-8-oxoguanine (8-oxoG). Has
CC       AP (apurinic/apyrimidinic) lyase activity and introduces nicks in
CC       the DNA strand. Cleaves the DNA backbone by beta-delta elimination
CC       to generate a single-strand break at the site of the removed base
CC       with both 3'- and 5'-phosphates (By similarity).
CC   -!- CATALYTIC ACTIVITY: Hydrolysis of DNA containing ring-opened 7-
CC       methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-
CC       methyl)formamidopyrimidine.
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.
CC   -!- COFACTOR: Binds 1 zinc ion per subunit (By similarity).
CC   -!- SUBUNIT: Monomer (By similarity).
CC   -!- SIMILARITY: Belongs to the FPG family.
CC   -!- SIMILARITY: Contains 1 FPG-type zinc finger.
