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.
