X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.00	293	2.3 M AMMONIUM SULFATE 50MM POTASSIUM PHOSPHATE PH 7.0 CRYSTALS WERE REDUCED USING 20MM SODIUM DITHIONITE. THE CRYSTAL WAS TRANSFERRED TO A SOLUTION CONTAINING 2.3 M AMMONIUM SULFATE, 50 MM PHOSPAHTE BUFFER PH 7 AND 15 % GLYCEROL. O2 WAS INTRODUCED UNDER 15 ATM PRESSURE FOR 2 MINUTES AT -20 DEGREES. THE DIOXYGEN SPECIES FORMED UNDER THESE CONDITIONS WAS REDUCED UPON X-RAY EXPOSURE AND THE RESULTING STRUCTURE REPRESENTS A MIXTURE OF STATES.
