Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 6.5 298 Crystals were grown by vapor diffusion at room temperature in 24 well Cryschem sitting drop plates (Hampton Research, Aliso Viejo, CA) with 600 microleters reservoirs of 25% PEG 3350 in 0.10 M MES buffer at pH 6.5. The protein droplets were of 8ul volume and consisted of equal parts of a 20 to 30 mg/ml protein stock solution and the reservoir solution. Crystals usually appeared and grew to full size within one to two weeks. Rhombohedral crystals were thin needles of indeterminate cross-section
