Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7	298	The crystals were grown in 1.4 M NaKPO4 pH 7.0, by mixing equal volumes of the precipitant solution and 13 mg/mL protein in binding buffer (500 mM NaCl, 50 mM Tris pH 8.0). The crystal was soaked for 1 hour in a solution containing 2 M NaBr., VAPOR DIFFUSION, HANGING DROP, temperature 298.0K
