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) when paired with C, G or T, as well as methyl-faPy (formanidopyrimidine residues) in poly(dG-dC) and spiroiminodihydantoin:C base pairs. Unlike its E.coli ortholog has no activity on 8-oxoG:A. 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. Cleaves ssDNA containing an AP site. Complements the H2O2 sensitivity of an M.smegmatis fpg disruption mutant; upon expression in M.smegmatis excises 8-oxoG from dsDNA. Ref.3 Ref.4 Ref.5 |
| 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 |
| Induction | Expressed in mid-log phase. Ref.4 |
| Sequence similarities | Belongs to the FPG family. Contains 1 FPG-type zinc finger. |
