Abstract
The movement proteins of two tobamoviruses (tobacco mosaic virus, TMV, common strain U1 and cruciferous TMV strain) containing amino‐terminal hexahistidine affinity tags were overexpressed inEscherichia coli and purified by metal chelate affinity chromatography. Purified recombinant proteins were immobilized to a Ni2+‐chelate adsorbent and their ability to interact with full‐length genomic TMV RNA was tested. Here we report that binding of viral RNA to hexahistidine fusion movement proteins results in the formation of stable ribonucleoprotein complexes.Keywords
