the enzyme is important for the degradation of some specific substrates, e.g. the neuropeptide cholecystokinin. It is likely that the main biological function of tripeptidyl-peptidase II is to participate in a general intracellular protein turnover. This peptidase may act on oligopeptides generated by the proteasome, or other endopeptidases, and the tripeptides formed would subsequently be good substrates for other exopeptidases. Tripeptidyl-peptidase II activity is increased in sepsis-induced muscle wasting, a situation of enhanced protein turnover

tripeptidyl peptidase (TPP) is an exopeptidase that sequentially hydrolyzes tripeptides from the N-terminus of oligopeptides or polypeptides. Ala-Phe-pNA, Phe-pNA, Leu-pNA, and N-terminal-blocked peptides (Cbz-Ala-Ala-Phe-pNA and Cbz-Ala-Ala-Leu-pNA) are not hydrolyzed at all

TPP II additionally has an endopeptidase activity and is able to attack longer disordered peptides up to 75 amino acid residues.Three cleavage sites after proline residues are noted, the endopeptidase activity is more promiscuous than expected, and certainly different from the specificity of the exopeptidase activity. No carboxypeptidase activity has been detected
