Template:Lowercase title Template:Infobox enzyme dATP(dGTP)—DNA purinetransferase (Template:EC number) 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.
