RNA DEPENDENT RNA POLYMERASE FROM DSRNA BACTERIOPHAGE PHI6 PLUS INITIATION COMPLEX
OverviewOverview
In most RNA viruses, genome replication and transcription are catalysed by, a viral RNA-dependent RNA polymerase. Double-stranded RNA viruses perform, these operations in a capsid (the polymerase complex), using an enzyme, that can read both single- and double-stranded RNA. Structures have been, solved for such viral capsids, but they do not resolve the polymerase, subunits in any detail. Here we show that the 2 A resolution X-ray, structure of the active polymerase subunit from the double-stranded RNA, bacteriophage straight phi6 is highly similar to that of the polymerase of, hepatitis C virus, providing an evolutionary link between double-stranded, RNA viruses and flaviviruses. By crystal soaking and co-crystallization, we determined a number of other structures, including complexes ... [(full description)]
