Core tip: Proteins that are involved in the replication cycle of hepatitis C virus are relevant targets for antiviral therapies. Their dynamical properties, however, cannot be sufficiently studied in experiments yet. Alternatively, owing to the available power of modern computers, the mechanism by which they operate can be investigated in computer experiments using appropriate models. In this regard, considerable progress has now been achieved for the viral helicase protein and the obtained results, in combination with experimental data, have significantly improved our understanding of its activity.
