Abstract

High yields of toxic shock syndrome toxin-1, from Staphylococcus aureus, have been purified (>99%) using a novel, simple, two-step procedure involving dye ligand chromatography. Crystals suitable for X-ray diffraction work were obtained by vapour diffusion using ammonium sulphate and polyethylene glycol as precipitants. They belong to the orthorhombic space group C2221, with unit cell dimensions a = 108·6 A ̊, b = 177·6 A ̊ and c = 97·5 A ̊, with three molecules per asymmetric unit. The crystals diffract to at least 2·5 Å resolution and are suitable for three-dimensional X-ray structural analysis.
