WebAug 13, 2024 · The enzyme at the binding site on myosin is called ATPase. The energy released during ATP hydrolysis changes the angle of the myosin head into a “cocked” position. The myosin head is then in a position for further movement, possessing potential energy, but ADP and Pi are still attached. WebMyosin is a family of filamentous motor protein that is divided into different classes or groups. These classes differ concerning their structure, location of genes, and functions. Some of the major classes of myosin are discussed below.
