== Publication Abstract from PubMed == | |||
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. | |||
