The hepatopancreas of squid (Illex illecebrosus) extract contains a wide range of carboxypeptidase (CP) activities based on hydrolysis of N-CBZ-dipeptide substrates. SDS-PAGE zymograms with N-CBZ-Phe-Leu substrate revealed three activity zones (CP-I, 23 kDa; CP-II, 29 kDa; CP-III, 42 kDa). CP-I

Human platelets were investigated for activity of the acidic carboxypeptidases: cathepsin A, lysosomal carboxypeptidase B and prolyl-carboxypeptidase. It was found that the main acidic carboxypeptidase in human platelets had cathepsin A activity. No activity of lysosomal carboxypeptidase B and prolyl-carboxypeptidase
