Background: DPPII/QPP/DPP7

Dipeptidyl-peptidase II (DPPII) is identical to quiescent cell proline dipeptidase (QPP) and dipeptidylpeptidase 7 (DPP7) (1, 2). It shares some substrate and cleavage specificity with DPPIV/CD26, DPP8, DPP9 and seprase/FAP (fibroblast activation protein), members of the S09 family of serine proteases. As prolyl proteases that cleave proteins and peptides after proline residues, these enzymes have high potential for drug discovery (3, 4). However, DPP7 is not a member of the S09 family, but a member of the S28 family that also includes lysosomal Pro‑X carboxypeptidase/prolylcarboxypeptidase/PRCP and thymus-specific serine peptidase/PRSS16 (2). The human DPP7 precursor consists of a signal peptide (aa 1‑21) and a mature chain (aa 22‑492). The purified rhDPP7 is active against Lys-Pro-AMC and Lys‑Ala‑AMC. Its activity against Lys-Pro-AMC is approximately 10-fold of that against Lys-Ala-AMC under otherwise identical conditions.
