IntEnz Enzyme Nomenclature
EC 3.4.16.5
Names
cathepsin A
deamidase
lysosomal carboxypeptidase A
lysosomal protective protein
phaseolin
serine carboxypeptidase I
Reaction
- Release of a C-terminal amino acid with broad specificity.
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 3.4.12.1 and EC 3.4.21.13, and included in EC 3.4.16.1. This enzyme is probably also identical to lysosomal tyrosine carboxypeptidase, formerly EC 3.4.16.3.
