SUMMARY To elucidate the changes of “myosin B” during storage of rabbit muscle, investigation was made of the dissociation of “myosin B” into myosin A and actin, their content of “myosin B,” and the interaction of “myosin B” with ATP. The approximate contents of myosin A and actin in “myosin B” were variable, showing a maximum content of actin in “myosin B” extracted from the muscle at 2 days after slaughter. This can also be inferred from changes of viscosity and the salting‐out curve of “myosin B,” as recently shown. Moreover, the interaction between actin and myosin A in “myosin B” became less strong with the progress of aging.
