Pro- and alpha- or gamma-Glu-derivatives are slowly hydrolyzed, when a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide. Glu350 is involved in catalysis, the enzyme in lung is identical with the p146 type II alveolar epithelial cell antigen

in combination with CD26/dipeptidyl peptidase IV, aminopeptidase N processes chemokine ligand CXCL11, but not CXCL8, to generate truncated CXCL11 forms. The truncated CXCL11 fails to induce an intracellular calcium increase but is still able to bind and desensitize CXCR3 for intact CXCL11 signaling. Truncated CXCL11 fails to attract lymphocytes, and further processing by aminopeptidase N results in significant reduction of inhibition of HMVEC migration
