Preliminary X-ray diffraction analysis of crystals of tomato aspermy virus (TAV)

Tomato aspermy virus (TAV) is a member of the T = 3 cucumovirus group, and the chrysanthemum strain (C‐TAV) has been crystallized in a form suitable for X‐ray structural analysis. The crystals, which grow in 14–17% ethanol at pH 8.5, are of orthorhombic space group I 222 with unit cell dimensions of a = 295.1 Å, b = 320.5 Å, and c = 383.6 Å. There are two T = 3 virus particles in the unit cell, which means that they must be centered at 0,0,0 and...
