Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.5	298.0	Protein Solution: 0.16 mM protein, 0.5 M KCl, 50 mM Tris Cl (pH 7.5), 1 mM DTT, 10% glycerol, 1 mM IMP Well Solution: 2.2 M ammonium sulfate, PEG 550 MME, 0.1 M Tris Cl (pH 7.5), 10% glycerol, 0.01 mM beta-mercaptoethanol IMP does not bind in crystal due to excess ammonium sulfate. Crystallization is reproducible in the absence of IMP. , VAPOR DIFFUSION, HANGING DROP, temperature 25K
