Crystallisation was performed anaerobically at 20 degree Celsius using the sitting drop method on 96-Well MRC 2-Drop polystyrene Crystallisation Plates (SWISSCI) in a Coy tent containing a N2/H2 (97:3%) atmosphere. The reservoir chamber was filled with 90 ul of crystallisation condition and the drop was formed by spotting 0.6 ul protein with 0.6 ul of 20% (w/v) PEG 6,000; 100 mM MES pH6 and 200 mM Ammonium chloride. The protein was crystallized at 13.0 mg/ml in 25 mM Tris/HCl pH 7.6, 2 mM dithiothreitol, 1 mM flavin adenine dinucleotide and 1 mM Flavin mononuleotide and 10% (v/v) glycerol. Crystals were cryo-protected by soaking in 20% (w/v) PEG 6,000; 100 mM MES pH6 and 200 mM Ammonium chloride supplemented with 30% v/v glycerol for a few seconds. |
