The native peptide, PLARTLSVAGLPGKK (cat# 22511), is a selective substrate for CaM kinase II and protein kinase C. It is a poor substrate for phosphorylase kinase and is not phosphorylated by myosin light chain kinase. The sequence of PLARTLSVAGLPGKK is homologous to phosphorylation site 2 in glycogen synthase. The relative Vmax/Km ratios of the peptide for different kinases are 100 for CaMK II, 22 for protein kinase C, 2 for phosphorylase kinase, and 0.5 for myosin light chain kinase respectively.
