X-RAY DIFFRACTION	?	293	SpaO(232-297) was concentrated to 8mg/mL and crystallized with 35% PEG400, 200mM calcium acetate, 100mM sodium acetate pH=5.0. Crystals were cryoprotected in the mother liquor. 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.
