An enzyme that breaks down ATP to two molecules called ADP and inorganic phosphate.
ATPase are proteins that cleave adenosine triphosphate (ATP) to adenosine diphosphate (ADP). This reaction releases energy, which is usually used to drive some other energy-requiring reaction mediated by the ATPase. For instance, Na/K-ATPase pumps Na+ out of cells and K+ into cells using the energy generated from the ATPase reaction. Another example is myosin ATPase, where the energy generated by the ATPase is used for muscle contraction.

An enzyme that catalyzes the hydrolysis of ATP. Usually, the hydrolysis reaction is coupled to another process, like in helicases.
One of a large group of enzymes that catalyze hydrolysis of ATP to yield ADP and inorganic phosphate with release of free energy. Theses enzymes normally are associated with cellular membranes or cytoskeletal structures and the energy released is utilized in some coupled activity such as active transport, muscle contraction, unwinding of DNA, or movement of cilia and flagella.
ATPases are a class of enzymes that catalyze the decomposition of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free phosphate ion. This dephosphorylation reaction releases energy, which the enzyme (in most cases) harnesses to drive other chemical reactions that would not otherwise occur. This process is widely used in all known forms of life.
