X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6.0	293	[Fe]-hydrogenase was crystallized under red light condition, in an anaerobic tent containing a gas phase of 100% N2 by the sitting drop vapuor diffusion method. The crystallization drops contained 0.7 ul of 30 mg.ml-1 protein and 2 mM methenyl-H4MPT+ mixed with 0.7 ul of 0.1 M MES pH 6.0 and 0.8 M ammonium sulfate and spotted on 96-well 2-drop MRC crystallization plates in polystyrene (Molecular Dimensions, Suffolk, UK). The best crystal appeared within 2.5 months.
