Methylated messenger RNA synthesis in vitro by purified reovirus.

چکیده

Purified human reovirus contains RNA methylase activity in addition to an RNA polymerase. Virions incubated under appropriate conditions in the presence of S-adenosyl-L-methionine synthesize mRNA that is specifically methylated in the 5'-terminal guanosine. Alkaline digestion of the methylated RNA released a 5'-terminal dinucleotide, ppG'pCp, indicating that the guanosine contains 2'-O-methylribose. The possible roles of methylation in viral and cellular mRNA function is discussed.

Methylation-dependent translation of viral messenger RNAs in vitro.

Methylated reovirus and vesicular stomatitis virus mRNAs, synthesized in vitro in the presence of S-adenosylmethionine by the virion-associated polymerases (RNA nucleotidyltransferases, EC 2.7.7.6), stimulate protein synthesis by wehat germ extracts to a greater extent than unmethylated mRNAs. Addition of S-adenosylmethionine to a cell-free extract programmed with unmethylated mRNA stimulates p...

Formation and characteristics of reovirus subviral particles in interferon-treated mouse L cells.

We examined the early phase of reovirus replication in interferon-treated L cells. No difference was detected in the adsorption of virus to cells, the rate and extent of conversion of parental virions to sub-viral particles (SVPs), and the protein and double-stranded RNA composition of the SVPs when comparing reovirus infection of the interferon-treated and control cells. Furthermore, when test...

Translation of reovirus messenger RNAs synthetesized in vitro into reovirus polypeptides by several mammalian cell-free extracts.

Single-stranded reovirus RNA, synthesized in vitro by reovirus cores, functioned as messenger RNA in cell-free extracts prepared from several mammalian cells: Krebs II mouse ascites cells, mouse L cells, Chinese hamster ovary cells, HeLa cells, and rabbit reticulocytes. As shown by acrylamide gel electrophoresis, all eight polypeptides known to be specified by reovirus were synthesized in the r...

Viral RNA polymerases: electron microscopy of reovirus reaction cores.

The Kleinschmidt technique has been used to observe reovirus cores that have synthesized messenger RNA. Some individual viral cores probably synthesize all ten messenger RNA molecules in vitro. Each messenger RNA molecule appears to be attached to a different site on the core surface, implying that there are probably a number of different enzymic sites in each core.

Formation of a mammalian initiation complex with reovirus messenger RNA, methionyl-tRNA F , and ribosomal subunits.

Previous data demonstrated that reovirus mRNA, synthesized in vitro with the particulate RNA transcriptase of reovirus cores, efficiently directs the synthesis of polypeptides in vitro. The present studies indicate that all of the three size classes of reovirus mRNA produced in vitro can form protein initiation complexes with rat liver [(36)S]Met-tRNA(F) and incubated 40S and 60S ribosomal subu...
