Structural insights into polymerase-catalyzed FAD capping of hepatitis C virus RNA

Abstract The RNA polymerase NS5B of HCV is capable of catalyzing the addition of flavin adenine dinucleotide (FAD) to its RNA as a 5′ cap structure, aiding the virus in evading host immune responses. However, the exact mechanism underlying the 5′-FAD capping process of HCV RNA remains to be elucidat...
