WebThe myosin head first attaches to actin together with the products of ATP hydrolysis, performs a power stroke associated with release of hydrolysis products, and detaches from actin upon binding with new ATP. The detached myosin head then hydrolyses ATP, and performs a recovery stroke to restore its initial position. WebBecause the head is attached to actin, this change in the shape of myosin causes the actin filament to “slide” past the myosin (the myosin “power stroke”). (4) • Binding of ATP to the myosin head domain causes the domain to detach from the actin filament and return to its original conformation. (5) • The myosin then hydrolyses the ...
