Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 6.9 293 ~0.9 mM of bMGL(D196N) was mixed with 180 mM 1-(rac)-lauroyl glycerol dissolved in 99% EtOH to achieve a final protein-ligand ratio of 1:5. The protein-ligand mixture was incubated at 4 C for 1 hour. Initial crystals were obtained using the Morpheus screen in condition A4. These crystals were used for preparing a seed stock. The optimised crystals were obtained in a drop containing 0.9 mM bMGL(D196N); 56 % v/v MPD, 0.1 M HEPES pH 6.9 and 1:1000 dilution of seed stock in a ratio of 2:2:1 respectively. 1-LG powder was added to these crystallization drops and the crystals were soaked for 8h., VAPOR DIFFUSION, HANGING DROP, temperature 293K
