INHIBITION OF THE HEPATITIS C VIRUS NS3/4A PROTEASE. THE CRYSTAL STRUCTURES OF TWO PROTEASE-INHIBITOR COMPLEXES (APO STRUCTURE)
OverviewOverview
The hepatitis C virus NS3 protein contains a serine protease domain with a, chymotrypsin-like fold, which is a target for development of therapeutics., We report the crystal structures of this domain complexed with NS4A, cofactor and with two potent, reversible covalent inhibitors spanning the, P1-P4 residues. Both inhibitors bind in an extended backbone conformation, forming an anti-parallel beta-sheet with one enzyme beta-strand. The P1, residue contributes most to the binding energy, whereas P2-P4 side chains, are partially solvent exposed. The structures do not show notable, rearrangements of the active site upon inhibitor binding. These results, are significant for the development of antivirals.
