Myosin ATPase (EC 3.6.4.1) is an enzyme with systematic name ATP phosphohydrolase (actin-translocating).[1][2][3] This enzyme catalyses the following chemical reaction:
- ATP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] ADP + phosphate
ATP hydrolysis provides energy for actomyosin contraction.
