1VAPOR DIFFUSION, HANGING DROP7293Holo protein at 10 mg/mL in 10 mM Tris pH 7, 100 mM NaCl, 5 mM DTT, 5% (v/v) glycerol was mixed with 2.4 M sodium malonate pH 7.0, 100 mM Bis-tris propane pH 7.0 in a 2:1 (v/v) ratio. Suitable crystals were soaked with 2 mM 5'-O-(N-(L-seryl)-sulfamoyl)N3-methyluridine in the crystallization solution containing additional 22% v/v glycerol.
