Diadenosine hexaphosphate hydrolase (AMP-forming)
Diadenosine hexaphosphate hydrolase (AMP-forming) (EC 3.6.1.60, hAps1, NUDT11 (gene), hAps2, NUDT10 (gene)) is an enzyme with systematic name P1,P6-bis(5'-adenosyl)hexaphosphate nucleotidohydrolase (AMP-forming).[1][2] This enzyme catalyses the following chemical reaction
- (1) P1,P6-bis(5'-adenosyl)hexaphosphate + H2O adenosine 5'-pentaphosphate + AMP
- (2) P1,P5-bis(5'-adenosyl)pentaphosphate + H2O adenosine 5'-tetraphosphate + AMP
