Enzyme Commission Primary Name: Xaa-Trp aminopeptidase
Enzyme Commission Synonyms: aminopeptidase W, aminopeptidase X-Trp, X-Trp aminopeptidase
Standard Gibbs Free Energy (ΔrG'°): -48.12524 kcal/mol [Latendresse13]
Enzyme Commission Summary:
Release of a variety of N-terminal residues (especially glutamate and leucine) from peptides, provided tryptophan (or at least phenylalanine or tyrosine) is the penultimate residue. Also acts on GluTrp, LeuTrp and a number of other dipeptides.
This is a glycoprotein containing Zn2+, from renal and intestinal brush border membranes.
