ENTRY       EC 3.4.18.1
NAME        Cysteine-type carboxypeptidase
            Lysosomal carboxypeptidase B
            Cathepsin B2
            Cathepsin IV
            Acid carboxypeptidase
CLASS       Hydrolases
            Acting on peptide bonds (peptidases)
            Cysteine-type carboxypeptidases
REACTION    Liberation of C-terminal amino acid residues, with broad
            specificity, but lacks action on C-terminal proline
SUBSTRATE   Peptide
            H2O
PRODUCT     Amino acid
            Peptide
COMMENT     Deaminates Z-Arg-NH2, but slows no action on the arylamide
            derivatives. Inhibited by thiol-blocking reagents.  Formerly
            included with EC 3.4.16.1.
