phosphorylation data on the peptides by the tyrosine kinase showed that the two beta-turn peptides were phosphorylated with vmax and km values comparable to those of the 13-residue-long arginine-containing synthetic peptide substrate having a sequence homologous to the autophosphorylation site of the lstra kinase .
