Abstract excerpt
Pulmonary endothelial aminopeptidase P (AmP) may be an important contributor to the inactivation of circulating bradykinin in certain species. To examine this possibility, we measured AMP activity in vivo and in vitro using Arg-Pro-Pro-[3H]benzylamide (3H-APPB) as substrate under conditions of first order enzyme kinetics. Utilizing multiple indicator dilution techniques, metabolism of 3H-APPB to Arg and...
