Hydrolases;
Acting on peptide bonds (peptidases);
Aminopeptidases
Reaction(IUBMB)
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
