Crystallization and preliminary X-ray diffraction studies of a novel killer toxin from a halotolerant yeast Pichia farinosa.

A killer toxin from a halotolerant yeast, Pichia farinosa strain KK1, was crystallized at high- and low-salt concentrations. Crystals from the high-salt solution belonged to the tetragonal space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell dimensions of a = b = 81.10, c = 118.
