Effect of the composition of the reaction mixture on the Ca(2+)-sensitivity of myofibrillar ATPase of rabbit skeletal muscle was investigated. The Ca(2+)-concentrations necessary for the half maximum ATPase activation were 2.95 x 10(-6) M at 50 mM KCl, 4.37 x 10(-6) M at 90 mM KCl and 5.25 x 10(-6) M at 130 mM KCl. Thus the Ca(2+)-sensitivity was definitely… CONTINUE READING
