Structures of additional crystal forms of Satellite tobacco mosaic virus grown from a variety of salts.

ABSTRACT: The structures of new crystal forms of Satellite tobacco mosaic virus (STMV) are described. These belong to space groups I2, P2₁2₁2 (a low-resolution form), R3 (H3) and P23. The R3 crystals are 50%/50% twinned, as are two instances of the P23 crystals. The I2 and P2₁2₁2 crystals were grown from ammonium sulfate solutions, as was one crystal in space group P23, while the R3 and the other P23 crystals were grown from sodium chloride, sodium bromide and sodium nitrate. The monoclinic and orthorhombic crystals have half a virus particle as the asymmetric unit, while the rhombohedral and cubic crystals have one third of a virus particle. RNA segments organized about the icosahedral twofold axes were present in crystals grown from ammonium sulfate and
