Crystallization Conditions

crystal ID	method	pH	temperature	details
1	VAPOR DIFFUSION, SITTING DROP	8.5	289.15	0.3 ul 1.9 mg/ml FphE (10mM HEPES pH 7.6, 100mM NaCl) were mixed with 0.3 ul of reservoir solution. Sitting drop reservoir contained 25 ul of 200mM Magnesium chloride hexahydrate, 100mM Tris pH 8.5, 25% PEG 2000 MME. Crystal appeared within ~30 days at 16C. It was frozen in a solution of ~25% glycerol, 75% reservoir.
