Amino acid sequences of peptides containing the phosphorylation site of bovine cardiac myosin light chain (L2) were determined. The site was localized to a serine residue in the tentative amino terminus of the light chain and is homologous to phosphorylation sites in other myosin light chains. Phosphorylation of bovine cardiac light chain by chicken gizzard myosin light chain kinase was Ca2+-calmodulin dependent. Kinetic data gave a Km of 107; microM and a Vmax of 23.6 mumol min-1 mg-1. In contrast to what has been observed with smooth muscle light chains, neither the phosphorylation site fragment of the cardiac light chain nor a synthetic tetradecapeptide containing the phosphorylation site were effectively phosphorylated by the chicken gizzard kinase. Phosphorylation of cardiac myosin light chains by chicken gizzard myosin light chain kinase, therefore, requires other regions of the light chain in addition to a phosphate acceptor site.
