1EVAPORATION293Protein was purified in buffer: 20 mM Hepes pH 8.0, 150 mM NaCl, 5 mM MgCl2 and 0.5 mM DTT. Crystals grew in five days at room temperature from hanging vapor diffusion drops with following condition: 0.1 M Citric acid pH 4.0, 20% PEG 3350. Crystals were cryoprotected in mother liquid with 40% PEG 3350 and flash frozen in liquid nitrogen.
