Molecular function

GO:0004002, GO:0042623

ATP hydrolase activity, ATP phosphohydrolase activity, adenosine 5'-triphosphatase activity, adenosine triphosphatase activity, adenosinetriphosphatase activity

Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient.

ATP monophosphatase activity

Note that this term is meant to specifically represent the ATPase activity of proteins using ATP as a source of energy to drive a reaction. If possible, gene products should also be annotated to a child of 'ATP-dependent activity ; GO:0140657', to capture their overall function.
