Model for myosin action







The binding of ATP dissociates myosin from actin. ATP hydrolysis then induces a conformational change that displaces the myosin head group. This is followed by binding of the myosin head to a new position on the actin filament and release of ADP and Pi. The return of the myosin head to its original conformation drives actin filament sliding.
