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