    摘要: A highly specific peptide substrate for protein kinase C is composed in basic form of a serine or threonine amino acid residue flanked by groups of basic amino acids composed entirely of argenine, lysine or histidine or any combination of these amino acid residues. The peptide, which is phosphorylated by the protein kinase C, can be used in a direct or competitive assay for protein kinase C by employing radiolabeled ATP. In the phosphorylation process the phosphate is transferred from the ATP by the protein kinase C to the peptide of the present invention.
