Phosphorylation Reaction of Vertebrate Smooth Muscle Myosin: An Enzyme Kinetic Analysis? Apolinary Sobieszek Institute of Molecular Biology, Austrian Academy of Sciences, A-5020 Salzburg, Austria Received July 16, 1984
Phosphorylation of vertebrate smooth muscle myosin or its isolated 20 000-dalton light chains by myosin light-chain kinase (MLCK) was found to follow first-order kinetics not only a t low ([MI
