WebMyosin binds to actin at a binding site on the globular actin protein. Myosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy. The process works in a cycle (called the “cross bridge cycle”) like this: WebMyosin. Myosins are a family of ATP-dependent motor proteins. Myosin II is the major contractile protein involved in eukaryotic muscle contraction by "walking" along actin … WebActin has binding sites for myosin attachment.
