Interaction of C-protein with myosin, myosin rod and light

WebThe binding of the myosin heads to the muscle actin is a highly regulated process. When a muscle is resting, actin and myosin are separated. To keep actin from binding to the active site on myosin, regulatory proteins block the molecular binding sites. These regulatory proteins are tropomyosin and troponin. WebThe binding site on myosin appears to be in the subfragment-2 region since proteolytically derived myosin rod and heavy meromyosin bind as well as whole myosin, whereas S-1 …
