Inhibition of the aspartic proteinase from HIV‐2

Abstract

Kinetic constants were determined for the interaction of the HIV-2 aspartic proteinase with a synthetic substrate and a number of inhibitors at several pH values. Acetyl-pepstatin was more effective towards HIV-2 proteinase than the renin inhibitor, H-261; this effect is exactly the opposite from that observed previously for the proteinase from the HIV-1 AIDS virus.
