ATPase


ATPase
An enzyme capable of releasing the terminal (g) phosphate from ATP, yielding ADP and inorganic phosphate. The description could mislead, because in most cases the enzymic activity is not a straightforward hydrolysis, but is part of a coupled system for achieving an energy-requiring process, such as ion-pumping or the generation of motility.
