DE   dATP(dGTP)--DNA purinetransferase.
CA   (1) dATP + depurinated DNA = deoxyribose triphosphate + DNA.
CA   (2) dGTP + depurinated DNA = deoxyribose triphosphate + DNA.
CC   -!- The purine residue is transferred on to the apurinic site forming a
CC       normal glycosylic bond.
CC   -!- dATP reacts at sites of the double-stranded depurinated DNA that lack
CC       adenine, and dGTP at sites that lack guanine.
