Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	4.0	281.15	The reconstituted [Fe]-hydrogenase holoenzyme from M. aeolicus was crystallized in the anaerobic tent with gas phase 95%N2/5%H2 using 96-well 2-drop MRC Crystallization Plates (Molecular Dimensions, Suffolk, UK). For the initial screening, 0.7-ul of 24 mg/ml reconstituted [Fe]-hydrogenase was mixed with 0.7 ul of reservoir solution of crystallization kits under yellow light and incubated under the dark condition. The best diffracting crystal was obtained in one month in the crystallization reservoir solution containing 20% w/v polyethylene glycol 3350, 100-mM tri-sodium citrate pH 4.0 and 200-mM tri-sodium citrate.
