Triphosphate moiety
WebOct 21, 2016 · The dATP triphosphate moiety lies in a depression on the ModC surface, with residues Lys 165, Ser 167, and His 169 from motif II and Arg 291 and Lys 297 from motif III, making direct hydrogen bonds with the phosphate groups ( Fig. 2A and fig. S3). WebThe RTPase function, which cleaves the 5′ triphosphate of an RNA (Fig. 7 A), is required as the first step to generate a type 1 cap structure at the 5′ end of viral genome (Fig. 3). NS3 also carries out a helicase reaction that unwinds dsRNA in a 3′ to 5′ direction, and requires an overhang at the 3′ end of the dsRNA.
