In the contractile cycle ATP binding causes a conformational change, which detaches the myosin S1 unit from actin. Then the active site closes, and ATP is hydrolysed to Pi and ADP, leading to the subsequent reattachment of the S1 with the actin. The conformational changes of the acting-binding pocket and the opening and closing of the nucleotide-binding pocket cause the strong and weak acting binding states of myosin, allowing muscle contraction.
