Method	pH	Temprature	Details
X-RAY DIFFRACTION	?	277	SpaO(145-213) + SpaO (232-297) was concentrated to 12mg/mL and crystallized with 25% PEG400, 10% isopropanol, 100mM sodium citrate pH=5.6 at 277K. Microseeding was employed to enhance crystal uniformity and diffraction. Briefly, crystals to be seeded were harvested in precipitant solution and vortexed in a microfuge tube with a small stir bar for ~60 seconds. The slurry of microseeds was serially dilluted (5-10-fold steps) in precipitant solution and 5 selected microseed-precipitant mixtures were mixed with fresh protein as in a normal hanging drop experiment. Crystals were cryoprotected in mother liquor with the PEG400 concentration raised to 37.5%.
