Xaa-Xaa-Pro tripeptidyl-peptidase.
based on mapping to UniProt Q7MUW6
Hydrolysis of Xaa-Xaa-Pro-|-Yaa- releasing the N-terminal tripeptide of a peptide with Pro as the third residue (position P1) and where Yaa is not proline.
-!- This cell-surface-associated serine exopeptidase is found in the Gram-negative, anaerobic bacterium Porphyromonas gingivalis, which has been implicated in adult periodontal disease. -!- The enzyme releases tripeptides from the free amino terminus of peptides and small proteins, such as interleukin-6. -!- The enzyme possesses an absolute requirement for a proline residue at the P1 position but is completely inactivated by a proline residue at the P1' position. -!- The size of the peptide does not affect the rate of reaction.
