Xaa-Xaa-Pro tripeptidyl-peptidase (EC 3.4.14.12 prolyltripeptidyl amino peptidase prolyl tripeptidyl peptidase prolyltripeptidyl aminopeptidase PTP-A TPP) is an enzyme. It catalyses the following chemical reaction 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 prolineThis cell-surface-associated serine exopeptidase is found in the Gram-negative anaerobic bacterium Porphyromonas gingivalis.
