Nd. Rawlings et Aj. Barrett, DIPEPTIDYL-PEPTIDASE-II IS RELATED TO LYSOSOMAL PRO-X CARBOXYPEPTIDASE, Biochimica et biophysica acta. Protein structure and molecular enzymology, 1298(1), 1996, pp. 1-3
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 t
hat the enzyme is homologous with lysosomal Pro-X carboxypeptidase (EC
3.4.16.2), and belongs to peptidase family S28 in dan SC. This is con
sistent with a number of biochemical similarities between these two pr
olyl bond-cleaving serine peptidases. DPP II is not related to granzym
es, as was suggested by Huang et al.
