IUBMB Enzyme Nomenclature


Accepted name: carboxypeptidase C

Reaction: Release of a C-terminal amino acid with broad specificity

Other names: carboxypeptidase Y; serine carboxypeptidase I; cathepsin A; lysosomal protective protein; deamidase; lysosomal carboxypeptidase A; phaseolin

Comments: A carboxypeptidase with optimum pH 4.5-6.0, inhibited by diisopropyl fluorophosphate, and sensitive to thiol-blocking reagents (reviewed in [1]). Widely distributed in eukaryotes. Type example of peptidase family S10. Formerly EC and EC, and included in EC
