Metabolite Identification
Common Name2,6-Diamino-4-hydroxy-5-N-methylformamidopyrimidine
Description2,6-Diamino-4-hydroxy-5-N-methylformamidopyrimidine is a methylated derivative of 2,6-Diamino-4-hydroxy-5-N-formamidopyrimidine or FapyGua. It is produced by DNA-formamidopyrimidine glycosylase (EC 3.2.2.23). This enzyme catalyzes the hydrolysis of DNA containing ring-opened 7-methylguanine residues, releasing 2,6-diamino-4-hydroxy-5-(N-methyl)formamidopyrimidine. More specifically, this enzyme catalyzes the removal of oxidized purine bases by cleaving the N-C1' glycosidic bond between the oxidized purine and the deoxyribose sugar. The reaction involves the formation of a covalent enzyme substrate intermediate. Release of the enzyme and free base by a beta-elimination or a beta, gamma-elimination mechanism results in the cleavage of the DNA backbone 3' of the apurinic (AP) site. The presence of this compound in urine is indicative of oxidative damage to DNA (oxidized purine base lesions).
