Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	8.0	289	Crystals were produced by sitting drop vapor diffusion with an equal volume of the protein, Msk1-C terminal domain (PID7059-1, CID101276) at 5 mg/ml with 1.5mM UCB1590591/BSI106893 in 25mM HEPES pH 7.5, 150mM NaCl, 5% Glycerol, 5mM BME and a crystallization buffer containing 100mM sodium malonate pH 8.0, 100mM Tris pH 8.0, 30% w/v PEG 1000 (tray ID 305760, well F2, CID101276_fine1 screen). Crystals were soaked for 4 days in 2.5ul of reservoir with 1mM UCB1590956/BSI100006.Crystals were cryo protected with 20% EG + compound and vitrified in in liquid N2. Puck ID WJP9-1
