In enzymology an ATP diphosphatase (EC 3.6.1.8) is an enzyme that catalyzes the chemical reactionATP + H2O AMP + diphosphateThus the two substrates of this enzyme are ATP and H2O whereas its two products are AMP and diphosphate.This enzyme belongs to the family of hydrolases specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is ATP diphosphohydrolase (diphosphate-forming).
