THE SOLUTION NMR STRUCTURE OF THE N-TERMINAL PROTEASE DOMAIN OF THE HEPATITIS C VIRUS (HCV) NS3-PROTEIN, FROM BK STRAIN, 20 STRUCTURES
Overview
The solution structure of the hepatitis C virus (BK strain) NS3 protein N-terminal domain (186 residues) has been solved by NMR spectroscopy. The protein is a serine protease with a chymotrypsin-type fold, and is involved in the maturation of the viral polyprotein. Despite the knowledge that its activity is enhanced by the action of a viral protein cofactor, NS4A, the mechanism of activation is not yet clear. The analysis of the folding in solution and the differences from the crystallographic structures allow the formulation of a model in which, in addition to the NS4A cofactor, the substrate plays an important role in the activation of the catalytic mechanism. A unique structural feature is the presence of a zinc-binding site exposed on the surface, subject to a slow conformational exchange process.
