Definitions for "ATPase"
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.
adenosine 5-triphosphatase
