X-RAY DIFFRACTION ? 293 17-22% PEG 2000 MME, 7-10% PEG 3000 and 0.1M HEPES pH 7.0. Protein crystallization was performed in 24-well sitting drop plates with a 1:1 ratio of protein to reservoir solution (final volume of 3 uL). Crystals were allowed to grow for at least 1 week at room temperature. Crystals at sizes appropriate for X-ray data collection were then cryoprotected with 2.5 uL of cryosolution (90% reservoir solution + 10% PEG 400.) Crystals were harvested with nylon loops and flash-frozen in liquid nitrogen.
