Abstract
Tryptic digestion of gizzard myosin resulted in the degradation of the 20K light chain (G1) to its 17K fragment, which could not be phosphorylated. The rapid loss of Ca2+-dependent activation of actomyosin ATPase activity accompanied the degradation of G1. Increase in the Ca2+-ATPase activity and decrease in the EDTA-ATPase activity of myosin accompanied the degradation of myosin heavy chain, but not the cleavage of G1.Keywords
