ATOMIC-RESOLUTION CRYSTAL STRUCTURE OF CHEMICALLY-SYNTHESIZED HIV-1 PROTEASE COMPLEXED WITH INHIBITOR MVT-101
Overview
The human immunodeficiency virus 1 (HIV-1) protease (PR) is an aspartyl, protease essential for HIV-1 viral infectivity. HIV-1 PR has one catalytic, site formed by the homodimeric enzyme. We chemically synthesized fully, active HIV-1 PR using modern ligation methods. When complexed with the, classic substrate-derived inhibitors JG-365 and MVT-101, the synthetic, HIV-1 PR formed crystals that diffracted to 1.04- and 1.2-A resolution, respectively. These atomic-resolution structures revealed additional, structural details of the HIV-1 PR's interactions with its active site, ligands. Heptapeptide inhibitor JG-365, which has a hydroxyethylamine, moiety in place of the scissile bond, binds in two equivalent antiparallel, orientations within the catalytic groove, whereas the reduced isostere, ...
