WebThe kinetics of skeletal muscle myosin were studied by many investigators and by about 1970, several properties had been established that seemed confusing or paradoxical: 1. Actin and myosin bind tightly together in the absence of ATP. This observation explains why muscles are stiff after death (rigor mortis). 2. WebSix actin filaments surround each myosin filament and the active sites of an actin filament are available to three different myosin filaments in the myofibril of skeletal muscle fibre.
