title: [Effect of carboxycathepsin on biological activity of bradykinin].
abstract: An effect of carboxycathepsin (peptidyl-dipeptidase EC 3.4.15.1) from bovine kidney on bradikinine was studied. The bradikinine activity was determined by monitoring the rat uterine horn retraction. Carboxycathepsin caused rapid inactivation of bradikinine (440-500 mcg of bradikinine/mg/min). The rate of bradikinine inactivation depended on the incubation time, content of the enzyme and substrate in the samples. In presence of EDTA carboxycathepsin did not inactivate bradikinine.
