DATP(dGTP)—DNA_purinetransferase
dATP(dGTP)—DNA purinetransferase (EC 2.6.99.1) is an enzyme with systematic name dATP(dGTP):depurinated-DNA purine transferase.[1][2] This enzyme catalyses the following chemical reaction
- (1) dATP + depurinated DNA deoxyribose triphosphate + DNA
- (2) dGTP + depurinated DNA deoxyribose triphosphate + DNA
The purine residue is transferred on to the apurinic site forming a normal glycosylic bond.
