| 1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 289.15 | 0.4 uL ~8.0 mg/mL FphF (10 mM HEPES pH 7.5, 10 mM NaCl) were mixed with 0.07 uL ligand solution (~0.5 mM 4-Methylumbelliferyl heptanoate in 100% DMSO) and 0.4 uL of reservoir solution. Sitting drop reservoir contained 50 uL of 0.8 M Sodium formate, 0.1 M Tris pH 7.5, 10 % w/v PEG 8000 and 10 % w/v PEG 1000. Crystals were soaked for ~15 seconds in 75% reservoir solution and 25% glycerol prior to freezing in liquid nitrogen |
