The proteins of this virus are arranged along the genome in the following order: N terminal-core-envelope (E1)–E2–p7-nonstructural protein 2 (NS2)–NS3–NS4A–NS4B–NS5A–NS5B–C terminal. The mature nonstructural proteins (NS2 to NS5B) generation relies on the activity of viral proteinases. The NS2/NS3 junction is cleaved by a metal-dependent autocatalytic proteinase e… WebNS5A inhibitors bind to domain I of the NS5A protein and block its ability to regulate HCV replication within the replication complex, through an as-yet-unclear mechanism. They could inhibit both the cis and trans functions of NS5A and perturb the function of newly formed replication complexes through redistribution of this viral protein from ...
