Enzyme Information

3.6.1.61
Diadenosine hexaphosphate hydrolase (ATP-forming).
based on mapping to UniProt Q75UV1
(1) P(1),P(6)-bis(5'-adenosyl)hexaphosphate + H(2)O = 2 ATP. (2) P(1),P(5)-bis(5'-adenosyl)pentaphosphate + H(2)O = ATP + ADP. (3) P(1),P(4)-bis(5'-adenosyl)tetraphosphate + H(2)O = ATP + AMP.
-!- The enzyme hydrolyzes P(1),P(4)-bis(5-guanosyl) tetraphosphate very slowly (cf. EC 3.6.1.17).
