Abstract
1. Dipeptidyl peptidases (DPP) II and III from porcine spleen have been purified to homogeneity as assessed by disc gel electrophoresis, HPLC and chromatofocusing. 2. The enzyme are both inhibited by diisopropylfluorophosphate suggesting that the active site contains an essential serine residue, but they are also inhibited by a variety of other reagents. 3. The pI of DPP II is 4.8, that of DPP III, 4.0. 4. The former enzyme has a molecular weight of 97,000, the latter 66,000 and both are glycoproteins. 5. The enzymes are compared with those from other sources.Entities:
