ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8.5	277	Final crystallization conditions contained 1.5 micro l reservoir solution (0.5M MgCl2, 0.1M Tris pH 8.5 and 20% PEG 8000) and 1.5 micro L of 8.0 mg/ml LucY in 150mM NaCl, 50mM Tris pH 7.5.. Crystals were cryoprotected by transferring into Mitegen s LV CryoOil (MiTeGen, LLC) prior to mounting and were flash-frozen in liquid nitrogen. , VAPOR DIFFUSION, HANGING DROP, temperature 277K
