X-RAY DIFFRACTION 7.0 293.15 The purified protein was crystallised at a final concentration of 13 mg/ml with 2 mM ATP and 2 mM MgCl2 by spotting 0.7 ul of crystallisation solution with 0.7 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 3000, 100 mM Tris pH 7.0 and 200 mM calcium acetate. The crystal was soaked in the crystallisation solution supplemented with 20% glycerol prior to freezing in liquid nitrogen.
