Quantitation of reactivity of involucrin peptides. (A) Time course of reaction of peptides containing variable length of polyglutamine. (B) Stoichiometry of glycine ethyl-ester incorporated after 10-h incubation, expressed per mol of peptide. (C) Stoichiometry of same incorporation, expressed per mol of glutamine (complete reaction = 1 mol/mol of glutamine).
