IntEnz Enzyme Nomenclature


Accepted name:
DNA-formamidopyrimidine glycosylase
Other names:
2,6-diamino-4-hydroxy-5(N-methyl)formamidopyrimidine-DNA glycosylase
2,6-diamino-4-hydroxy-5N-formamidopyrimidine-DNA glycosylase
Fapy-DNA glycosylase
Fpg protein

formamidopyrimidine-DNA glycosylase
Systematic name:
DNA glycohydrolase [2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimide releasing]



May play a significant role in processes leading to recovery from mutagenesis and/or cell death by alkylating agents. Also involved in the GO system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine) from DNA.
