X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	8.5	298	The protein was dissolved at 42 mg/ml in 20 mM Tris-HCl, pH 8.0, 0.15 M NaCl, 5% glycerol and 2 mM DTT. Crystals were grown in hanging drops by mixing 2 microL protein solution with 2 microL well solution (28% PEG 4000, 0.1 M Tris-HCl, pH 8.5, 0.2 M MgCl2, 1 mM DTT and 7.5 mM glycyl-glycyl-glycine) at 21 deg C. For cryoprotection, the crystals were soaked in the well solution supplemented with 25% ethylene glycol, VAPOR DIFFUSION, HANGING DROP, temperature 298K
