phosphate incorporation into light chain declined after 1 min whereas isometric tension was maintained . beta-adrenergic inhibition of tension development was accompanied by a decrease in the rate and extent of phosphorylatable myosin light chain phosphorylation but was not associated with reduced affinity of myosin light chain kinase for calcium-calmodulin .
