Protein: Dipeptidyl-peptidase 7 (DPP-7) (DPP7) (EC 3.4.14.-) (B2RKV3)
Organism: Porphyromonas gingivalis (strain ATCC 33277 / DSM 20709 / CIP 103683 / JCM 12257 / NCTC 11834 / 2561)
Function: Catalyzes the removal of dipeptides from the N-terminus of oligopeptides. Shows a broad specificity for both aliphatic and aromatic residues in the P1 position, with glycine or proline being not acceptable in this position. Most potently cleaves the synthetic substrate Met-Leu-methylcoumaryl-7-amide (Met-Leu-MCA), Leu-Arg-MCA and Lys-Ala-MCA to a lesser extent. Is likely involved in amino acid metabolism and bacterial growth of asaccharolytic P.gingivalis, that utilizes amino acids from extracellular proteinaceous nutrients as energy and carbon sources.
Subcellular location: Cell outer membrane {ECO:0000269|PubMed:11096098}.
