A, B	PF02245	Methylpurine-DNA glycosylase (MPG) (Pur_DNA_glyco)	Methylpurine-DNA glycosylase (MPG)	Methylpurine-DNA glycosylase is a base excision-repair protein. It is responsible for the hydrolysis of the deoxyribose N-glycosidic bond, excising 3-methyladenine and 3-methylguanine from damaged DNA.	Domain
