X-RAY DIFFRACTION	?	293	Required amount of DNA to 2:1 (protein:DNA) stoichiometry was diluted in [20 mM Tris (pH8.0), 500 mM NaCl, 20 mM DTT] and protein was added to final concentration of 5 mg/mL. Crystals of MpARF2-DBD:DNA were obtained in 100 mM Tris pH 7-9, 18-33% PEG2KMME, 18.5% Glycerol by the sitting-drop vapor-diffusion method at 18 deg. C, in drops of 1 uL + 1 uL (protein:reservoir). Crystals appeared in less than a week. Cryo-cooling in liquid nitrogen was carried out using a cryo-protecting solution containing reservoir solution supplemented with 10% glycerol.
