Tobacco Mosaic Virus (PDB entry 2tmv)
Seventeen subunits of tobacco mosaic virus are shown here, arranged into a helical ring. Notice how the ring is a
little too small to fit all seventeen, so the ends have to overlap to form a lock-washer shape. The RNA (shown in
orange) fits into a groove in the protein subunits. Click on the buttons below to show the clusters of acidic amino
acids that are important in disassembly of the virus.
