1	VAPOR DIFFUSION, HANGING DROP	8.5	293	EhRho1-GTPgammaS at 5 mg/mL and and EhFormin1 at 10 mg/mL were mixed in crystallization buffer (50 mM Tris pH 8.0, 250 mM NaCl, 2.5% (v/v) glycerol, 5 mM DTT, 50 microM GTPgammaS, 1 mM magnesium chloride) and allowed to form a complex for 30 minutes at room temperature. The protein solution was then mixed 1:1 and equilibrated against crystallization solution (18% PEG 3350, 100 mM Tris pH 8.5, 200 mM magnesium chloride)., VAPOR DIFFUSION, HANGING DROP, temperature 293K
