Crystallization and preliminary X-ray study of a double-shelled spherical virus, rice dwarf virus.
Rice dwarf virus (RDV) is a double-shelled spherical plant virus consisting of 46,000 Mr capsid and 114,000 Mr core proteins and minor structural proteins, and containing 12 genome segments of double-stranded RNA. The virus has been crystallized in the cubic space group I23 with a = 789 A. There are two particles per unit cell, each positioned on a point of 23 symmetry. Packing considerations showed that the diameter of the virus particle is 693 A. The crystals diffract to at least 6.5 A resolution.
