2. Optimal results were obtained when crystals were grown by microseeding, with a reservoir solution containing 18% PEG 8000, 100 mM tris-HCl (pH 7.25), and 40 mM magnesium acetate. All cocrystals of AraC and arabinose were initially stabilized in a solution of 24% PEG 8000, 100 mM tris-HCl (pH 7.5), 40 mM magnesium acetate, and 0.2% (w/v) L-arabinose. For data collection, crystals were transferred to the above stabilizing solution plus 10% PEG 400 for 5 to 10 min and then flash-frozen in a small monofilament nylon loop placed in a cold nitrogen stream maintained at 100 K.

Crystals of the sugar-binding and dimerization domain of AraC in the absence of arabinose were grown by hanging-drop vapor diffusion with a reservoir solution of 20% PEG 4000, 0.1 M tris-HCl (pH 9.0), 5 mM KCl, and 0.2 M sodium acetate. Crystals were stabilized by sequential transfer into reservoir solutions containing increasing amounts of PEG 4000 in 4% increments (10 min in each step) until a concentration of 40% PEG 4000 was reached. Crystals were then directly flash-frozen in a 100 K nitrogen stream for data collection.

2-terminal arm of AraC is better defined in monomer B; therefore, that monomer was used for generation of all sugar-binding figures.
