X-RAY DIFFRACTION 8.5 293.15 The purified protein was crystallised at a final concentration of 32.7 mg/ml with 10 mM ATP and 10 mM MgCl2 by spotting 0.5 ul of crystallisation solution with 0.5 ul of protein sample. Crystallisation was done anaerobically in a Coy tent containing N2/H2 (97:3%) atmosphere. The screening was done at 20 degrees Celsius on 96-Well MRC 2-drop polystyrene (SWISSCI) plates containing 90 ul of crystallisation solution. The crystallisation solution in which crystals were obtained contained 20 % w/v polyethylene glycol 8000, 100 mM Tris pH 8.5 and 200 mM magnesium chloride. The crystals were soaked in the crystallisation solution supplemented with 30% glycerol prior freezing in liquid nitrogen.
