Effects of MLCK fragments and synthetic peptides on the actin-activated ATPase activity of dephosphorylated myosin. The actin-activated ATPase activity of myosin was examined in the presence of various concentrations of MLCK fragments and synthetic peptides under the conditions described in the legend to Fig. 2. (A) Effect of MLCK fragments. Filled circles, 777D/972E fragment; open triangles, 816M/972M fragment; filled triangles, telokin. (B) Effect of synthetic peptides. Filled circles, 777D/815S peptide; open circles, 796A/815S peptide; open triangles, 787S/815S peptide; filled triangles, 796A/834S peptide; crosses, 777D/795M.
