Xaa-Trp aminopeptidase (EC 3.4.11.16, aminopeptidase W, aminopeptidase X-Trp) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction
- 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 Glu!Trp, Leu!Trp and a number of other dipeptides
This glycoprotein contains Zn2+.
