Protein-primed RNA synthesis in vitro by the virion-associated RNA polymerase of infectious pancreatic necrosis virus.

Abstract:

:The 94-kDa virion-associated RNA-dependent RNA polymerase (RdRp) is present in infectious pancreatic necrosis virus in two forms: (i) as a free polypeptide (VP1) and (ii) as a genome linked protein (VPg) (J. G. Calvert et al., 1991, J. Gen. Virol. 72, 2563-2567). VP1 was guanylylated in vitro by incubating purified virus in the presence of [alpha2P]GTP. During further incubation in an in vitro RNA polymerase reaction mixture (in the presence of unlabeled GTP), the radiolabeled VP1-pG complex was "chased" via nascent RNA strands and replicative intermediates to a VP1-dsRNA complex. Labeled VP1-pG was recovered from the intermediate as well as from the final reaction products by digestion with RNase A and RNase V1, a dsRNA-specific nuclease. Analysis of the reaction products indicated that only the plus strands of the two genome segments were being synthesized in vitro which remained base-paired to their templates. The results suggest that in vitro transcription by the virion RdRp is primed by VP1 and then proceeds via an asymmetric, semiconservative, strand-displacement mechanism.

  • Newly synthesized dengue-2 virus nonstructural protein NS1 is a soluble protein but becomes partially hydrophobic and membrane-associated after dimerization.

    abstract::In a previous paper (G. Winkler, V. B. Randolph, G. R. Cleaves, T. E. Ryan, and V. Stollar, 1988, Virology 162, 187-196) we showed that the newly synthesized dengue-2 virus nonstructural protein, NS1, exists briefly as a monomer and then undergoes dimerization. We demonstrate here that the dimerization of NS1 is assoc...
