General annotation (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. HAMAP-Rule MF_00103

Catalytic activity

Hydrolysis of DNA containing ring-opened 7-methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimidine. HAMAP-Rule MF_00103

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. HAMAP-Rule MF_00103

Cofactor

Binds 1 zinc ion per subunit By similarity. HAMAP-Rule MF_00103

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00103

Sequence similarities

Belongs to the FPG family.

Contains 1 FPG-type zinc finger.
