Description
Dipeptidyl peptidase IV (DPP–IV) was purified to homogeneity from the crude extract of Porphyromonas gingivalis. Isoelectric point and molecular weight of DPP–IV were 6.1 and 66 kDa, respectively. Km value for the appropriate substrate (H–Gly–Pro–pNA) was 0.2₅ mM, and Vmax/Km was 0.₅2. Optimum pH for the activity was found at pH ₇.₅. DPP–IV was considered a serine enzyme.
