Vacuolar carboxypeptidase involved in degradation of small peptides. Digests preferentially peptides containing an aliphatic or hydrophobic residue in P1' position, as well as methionine, leucine or phenylalanine in P1 position of ester substrate (By similarity). Release of a C-terminal amino acid with broad specificity. Decreases strongly intracellular carboxypeptidase activity. Belongs to the peptidase S10 family.
