IntEnz Enzyme Nomenclature


Accepted name:
dATP(dGTP)—DNA purinetransferase
Systematic name:
dATP(dGTP):depurinated-DNA purine transferase



The purine residue is transferred on to the apurinic site forming a normal glycosylic bond. dATP reacts at sites of the double-stranded depurinated DNA that lack adenine, and dGTP at sites that lack guanine.
