Abstract
Mutant movement proteins of red clover necrotic mosaic dianthovirus (RCNMV), consisting of in-frame deletions or fusions with a maltose-binding protein, were produced in Escherichia coli using expression vectors. The ability of the mutant proteins to bind to ssRNA was tested by photochemical cross-linking and gel retardation. The results showed that the region between amino acids 181 and 225 of the RCNMV movement protein contains an ssRNA-binding domain.
