Abstract

Physical properties of actomyosin from either fresh or stored platelets have been compared. Actomyosin obtained from platelets after 3 days of storage contained myosin that was 60-80% degraded to myosin rod. No myosin rod was detected in fresh platelets. The platelet myosin rod is similar to the rod produced by limited proteolysis of skeletal muscle myosin.
