| Abstract: | 1. Paramyosin from squid mantle muscle inhibited the Mg-ATPase and the superprecipitation activities of actomyosin. 2. The inhibition was detected only when paramyosin forms a cofilament with myosin. 3. ATP-induced changes in the morphology of the cofilament of myosin and paramyosin are involved in the inhibition by paramyosin. |
