The West Nile virus (WNV) NS5 protein contains a methyltransferase (MTase) domain involved in RNA capping and an RNA-dependent RNA polymerase (RdRp) domain essential for virus replication. Crystal structures of individual WNV MTase and RdRp domains have been solved; however, the structure of full-length NS5 has not been determined. To gain more insight into(More)
The 66-kDa cytoplasmic inclusion protein of tamarillo mosaic potyvirus was purified to near homogeneity using organic solvent clarification, differential centrifugation and sucrose density gradient centrifugation. ATPase and GTPase activities were shown to co-purify with the 66-kDa protein. ATPase activity was stimulated up to fivefold in the presence of 20(More)
Transgenic Nicotiana benthamiana plants expressing an untranslatable version of the coat protein (CP) gene from the Tamarillo mosaic virus (TaMV) were either resistant to TaMV infection or recovered from infection. These phenotypes were the result of a post-transcriptional gene silencing (PTGS) mechanism that targeted TaMV-CP sequences for degradation. The(More)
