Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 4JJF
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 6 293 [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.
