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