ABP56919.1 | DNA-(apurinic or apyrimidinic site) lyase / Formamidopyrimidine-DNA glycosylase; PFAM: Formamidopyrimidine-DNA glycolase; Belongs to the FPG family. (286 aa) | ||||
mutM | Formamidopyrimidine-DNA glycosylase / DNA-(apurinic or apyrimidinic site) lyase; 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. (287 aa) |
