these data indicate that : 1 ) phosphorylation of the 20,000 dalton myosin light chain controls the uterine smooth muscle actomyosin interaction , 2 ) in the absence of actin , phosphorylation does not affect either the atpase of myosin or the size of the initial burst of phosphate and , 3 ) ca2+ is important in controlling the light chain kinase but not the actomyosin interaction .
