A kinetic analysis has been performed with purified wheat carboxypeptidase by the use of N-acyl dipeptides, Z-Gly-Pro-Leu-Gly (Z=benzyloxycarbonyl), angiotensin II and bradykinin.The values of kcat were dramatically influenced by amino acid residues occupying the penultimate position from the carbonyl terminus of substrates.The structure of the substrate did not appreciably affect the Km values. Key Word Index - Triticum aestivum; Gramineae; wheat; carboxypeptidase; peptides; kinetic parameters.
