Ec Number:	3.4.17.4
Cas Number:	9025-25-6

Gly-Xaa carboxypeptidase (glycine carboxypeptidase, carboxypeptidase a, carboxypeptidase S, peptidase alpha, yeast carboxypeptidase) is an enzyme.^{[1] [2]} This enzyme catalyses the following chemical reaction

Release of a C-terminal amino acid from a peptide in which glycine is the penultimate amino acid, e.g. Z-Gly!Leu

This enzyme is isolated from yeast.
