Vesicular stomatitis virus growth in Drosophila melanogaster cells. II. Modifications of viral protein phosphorylation.
The phosphoproteins of vesicular stomatitis virus released from infected Drosophila melanogaster cells were examined. The membrane (M) protein was more phosphorylated than after multiplication in chicken embryo cells, even in Drosophila cell cytoplasm before its association with cellular membranes. Analysis of phosphopeptides generated after partial proteolysis and of phosphoamino acids obtained after complete acid hydrolysis showed that M phosphorylation was quantitatively and qualitatively changed, while NS protein phosphorylation was only slightly modified.
