Protein

Formamidopyrimidine-DNA glycosylase

Gene
mutM, fpg, MG262.1
Organism
Mycoplasma genitalium (strain ATCC 33530 / G-37 / NCTC 10195)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

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 By similarity.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
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

Cofactori

Binds 1 zinc ion per subunit By similarity.UniRule annotation
