ID 3.6.1.41 DE bis(5'-nucleosyl)-tetraphosphatase (symmetrical). AN Ap4A hydrolase. AN diadenosine 5',5'''-P(1),P(4)-tetraphosphate pyrophosphohydrolase. AN diadenosinetetraphosphatase (symmetrical). AN dinucleosidetetraphosphatase (symmetrical). CA H2O + P(1),P(4)-bis(5'-adenosyl) tetraphosphate = 2 ADP + 2 H(+). CC -!- Also acts on bis(5'-guanosyl) tetraphosphate and bis(5'-adenosyl) CC pentaphosphate, and, more slowly, on some other polyphosphates, CC forming a nucleoside bisphosphate as one product in all cases (cf. CC EC 3.6.1.17).
