Degradation of bradykinin and lysylbradykinin was studied in plasma and serum, and the results were compared to those seen with mixtures of carboxypeptidase N and angiotensin-converting enzyme (ACE), the two recognized kininases in blood. Angiotensin-converting enzyme was an effective kininase in mixtures with carboxypeptidase N at physiologic concentration and digested bradykinin to the dipeptides Phe- Arg and Ser-Pro plus the pentapeptide Arg-Pro-Pro-Gly-Phe. Carboxypeptidase N slowly removed… CONTINUE READING
