the competitive inhibitory activity of the calmodulin binding regions is similar to the apparent km of 2.7 microm for phosphorylation of the 23-residue peptide analog of the smooth muscle myosin light chain and raises the possibility that the calmodulin binding region of the myosin light chain kinase may act as a pseudosubstrate inhibitor of the enzyme .
