The active site cleft of the HIV-1 protease (PR) is bound by two identical conformationally mobile loops known as flaps, which are important for substrate binding and catalysis. The present article reports, for the first time, an HIV-1 PR inhibitor

Biochemical and biophysical research communications, 171(1), 439-444 (1990-08-31)
Kinetic constants (Km,Kcat) are derived for the hydrolysis of a number of chromogenic peptide substrates by the aspartic proteinase from HIV-2. The effect of systematic replacement of the P2 residue on substrate hydrolysis by HIV-1 and HIV-2 proteinases is examined.

The protease (PR) of Murine leukemia virus (MLV) was expressed in Escherichia coli, purified to homogeneity and characterized by using various assay methods, including HPLC-based, photometric and fluorometric activity measurements. The specificity of the bacterially expressed PR was similar to

HIV-1 protease (PR) and two drug-resistant variants--PR with the V82A mutation (PR(V82A)) and PR with the I84V mutation (PR(I84V))--were studied using reduced peptide analogs of five natural cleavage sites (CA-p2, p2-NC, p6pol-PR, p1-p6 and NC-p1) to understand the structural and

By replacement of the P1' residue in a capsid/nucleocapsid cleavage site mimic with 4-NO2-phenylalanine (Nph), an excellent chromogenic substrate, Lys-Ala-Arg-Val-Leu*Nph-Glu-Ala-Met, for HIV-1 proteinase (kappa cat = 20 s-1, Km = 22 microM) has been prepared. Substitution of the Leu residue
