WebMar 31, 2009 · Abstract. Chronic infection with hepatitis C virus (HCV) affects 130 million people worldwide and is a major cause of liver cirrhosis and liver cancer. After translation of the HCV RNA genome into a polyprotein, 2 viral proteases process its non-structural protein (NS) region. While the essential chymotrypsin-like serine protease NS3–4A ... WebThe gray diamonds indicate partial cleavages by ER signal peptidases(s), leading to the production of E2p7NS2 polyprotein. The arrows indicate cleavages by NS2–3 and NS3– 4A proteases.
