WebMyosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy. ATP binding causes myosin to release actin, allowing actin and myosin to detach from each other. After this happens, the newly bound ATP is converted to ADP and inorganic phosphate, P i. WebFeb 7, 2024 · Supporting muscle contractions as actin filaments slide alongside myosin filaments. In muscle, actin molecules twist together to form a 'thin filament' which interdigitate with thick filament bundles of myosin (muscle protein).
