The COOH-terminal residue in peptide analogs of the phosphorylation site sequence in smooth muscle myosin light chains, Lys11-Lys12-Arg13-Ala-Ala-Arg16-Ala-Thr-Ser19 -(P)Asn20-Val21-Phe22-Ala23, were shown to have a strong influence on the kinetics of peptide phosphorylation. The peptides 11-19, 11-20, 11-21, 11-22, and 11-23

Although the amino acid residues that are important for peptide substrates of myosin light-chain kinase have been reported, those that are important for peptide inhibitors of this enzyme have not previously been investigated. Synthetic peptides based on the sequence Lys11-Lys12-Arg13-Ala-Ala-Arg16-Ala-Thr-Ser19
