pubmed:abstractText
Recently it has been reported that a membrane fraction can be isolated from West Nile virus-infected BHK cells which contains the viral nonstructural (NS) proteins as major constituents (Wengler et al., 1990). In this report we show that treatment of these membranes with subtilisin releases the carboxy-terminal segment of the NS 3 protein as a soluble protein of about 50 kDa apparent molecular weight. This molecule, which is called the p50-S protein, can be purified by standard chromatographic procedures. The p50-S protein binds to poly(A) and apparently represents a nucleoside triphosphatase which is stimulated in the presence of ssRNA molecules. The data represent experimental support for the predicted role of this segment of the NS 3 protein as an RNA helicase. Some properties of the p50-S protein are described and a possible function of this protein segment during RNA synthesis is discussed.
