Models of the TMV virion.

The early stages of tobacco mosaic virus assembly: Tobacco mosaic virus protein aggregate binds to the RNA origin-of-assembly loop; additional aggregates now bind to the initial complex, pulling the 5' end of the RNA up through the hole in the middle of the growing virus particle.

Subunits of TMV, viewed along the viral axis. Ribbon representation of protein subunits; space-filling model of RNA nucleotides.

Three subunits of TMV, viewed at right angles to the viral axis. Ribbon representation of protein subunits; ball-and-stick model of RNA nucleotides; carboxylate side chains involved in viral disassembly shown. Discussed by Namba, K., Patanayek, R. and Stubbs, G. (1989). Visualization of protein-nucleic acid interactions in a virus. J. Mol. Biol. 208, 307-325.

Ribbon representation of a single subunit of TMV coat protein, with carboxylate side-chains shown, and a semi-transparent electrostatic surface.

Electrostatic surface potential of a single coat protein subunit leaving the end of a TMV virion. Carboxylate groups involved in viral disassembly are marked.
