1VAPOR DIFFUSION, HANGING DROP2927 mg/mL protein concentration, 100 mM Tris pH 7.8, 10 % PEG6000, equal amounts of protein and reservoir. Following crystal formation (1-2 days), the crystals were transferred to soaking solution containing reservoir solution and 25 mM IMP. Crystals were then transferred to cryo solution containing an additional 20 % glycerol, soaked for ~2-5 min, and flash frozen in liquid nitrogen.
