Pepstatin inhibition of proteinase-free human renin.
The kinetics of inhibition of proteinase-free human renin and of pepsin by the carboxyl proteinase inhibitor pepstatin have been examined. Inhibition was of the tight-binding type with both enzymes. Inhibition of crude human renin was of the classical, freely reversible type, but most of the renin-like activity of the preparation was due to contaminating proteinases which could be separated chromatographically from the renin. These results clarify previous kinetic studies of pepstatin inhibition of human renin.
