The structure of the protein disk of tobacco mosaic virus to 5A resolution.
An electron density map of the TMV disk at 5A resolution has been obtained using isomorphous replacement and non-crystallographic symmetry. The polypeptide chain can be traced with little ambiguity. The axial contacts between protein subunits are unlike those in the virus, the disk being a more open structure apparently designed for rapid interaction with the RNA.
