title: Dipeptidyl-peptidase II is related to lysosomal Pro-X carboxypeptidase.
abstract: The N-terminal amino-acid sequence of pig dipeptidyl-peptidase II (EC 3.4.14.2; DPP II) recently published (Huang, K., Takagaki, M., Kani, K. and Ohkubo, I. (1996) Biochim. Biophys. Acta 1290, 149-156) proves that the enzyme is homologous with lysosomal Pro-X carboxypeptidase (EC 3.4.16.2), and belongs to peptidase family S28 in clan SC. This is consistent with a number of biochemical similarities between these two prolyl bond-cleaving serine peptidases. DPP II is not related to granzymes, as was suggested by Huang et al.
