| 1 | VAPOR DIFFUSION, SITTING DROP | 5.5 | 291.15 | 16 uL 11.2 mg/mL FphE (10 mM HEPES pH 7.5, 100 mM NaCl) were mixed with 6 uL Q41 (50 mM in DMSO) and incubated at 18C overnight. 0.15 uL FphE-Q41 solution was mixed with 0.3 uL of reservoir solution. Sitting drop reservoir contained 25 uL of 180 mM Potassium Thiocyanate, 100 mM Sodium acetate pH 5.5, 22.5% PEG 2000 MME. Crystal was frozen in a solution of ~25% glycerol, 75% reservoir. |
