UniProtKB - Q5F8Z9 (FPG_NEIG1)
Protein
Formamidopyrimidine-DNA glycosylase
Gene
mutM
Organism
Neisseria gonorrhoeae (strain ATCC 700825 / FA 1090)
Status
Functioni
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.UniRule annotation
Catalytic activityi
- Hydrolysis of DNA containing ring-opened 7-methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimidine.UniRule annotation EC:3.2.2.23
- 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.UniRule annotation EC:4.2.99.18
Cofactori
Zn2+UniRule annotationNote: Binds 1 zinc ion per subunit.UniRule annotation
