1	VAPOR DIFFUSION, HANGING DROP	8.5	293	Holo protein at 10 mg/mL in 10 mM Tris pH 7, 100 mM NaCl, 2.5 mM 2-mercaptoethanol was mixed with 0.1 M bis-tris propane pH 8.5, 0.1 M MgCl2, 20% w/v PEG 3350 and a crystal seed stock in a 0.75:1.0:0.25 (v/v) ratio. The seed stock was prepared in the same crystallization buffer. Suitable crystals were soaked with 2 mM 5'-O-(N-(L-Leucyl)-Sulfamoyl)N3-methyluridine in an equivalent precipitant solution supplemented with 22% v/v ethylene glycol.
