| dipeptidyl peptidase | A hydrolase occurring in two forms: Dipeptidyl peptidase I, dipeptidyl transferase, cleaving dipeptides from the amino end of polypeptides, dipeptidyl peptidase II, with properties similar to those of I, has a different specificity. (05 Mar 2000) |
| dipeptidyl peptidases | <enzyme> Dipeptidylpeptide hydrolases. Enzymes which cleave dipeptides from the amino terminal of a polypeptide. Dipeptidyl peptidase I, II, III, IV are known.
