Structure of tomato bushy stunt virus

The three-dimensional structure of tomato bushy stunt virus has been determined by X-ray crystallographic analysis to 16 Å resolution, using methods of multiple isomorphous replacement, together with methods based on non-crystallographic symmetry. The relative orientation of the three quasi-equivalent protein subunits is clearly defined in the map. The geometry of dimer contacts appears to be very similar at strict and local dyads, whereas...
