1	VAPOR DIFFUSION, SITTING DROP	7	293	Screening for crystallization used the Gryphon liquid handling system (Art Robbins Instruments). Crystals were grown using sitting drops (200 nL protein + 200 nL crystallization reagent) with 60 UL reservoirs of crystallization reagent in a 96-well high-throughput screen. Plate-shaped crystals were obtained at 20 degree C using Hampton Research NATRIX HT #38: 0.2 M ammonium acetate, 0.15 M magnesium acetate tetrahydrate, 5% (w/v) polyethylene glycol 4000, and 0.05 M HEPES sodium, pH 7.0, VAPOR DIFFUSION, SITTING DROP, temperature 293K
