X-RAY DIFFRACTION 8.5 293.15 The purified protein was crystallised at a final concentration of 18.3 mg/ml with 2 mM ADP 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 3350, 100 mM Bis-Tris propane pH 8.5 and 200 mM sodium nitrate. Sealed plates were stored inside the same anaerobic chamber where the crystallisation was performed. The crystals in complex with MgADP were soaked in the crystallisation solution supplemented with 20% ethylene glycol prior to freezing in liquid nitrogen.
