X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	9.0	277	Protein (8-10 mg/ml) was mixed with well solution (100 mM Glycine, pH 9.0, 20-30% PEG 550 MME)at a 1:1 ratio. Microseeding was employed to obtain better crystals. Nucleotides were incorporated by exchanging drop and resevoir solutions with 20 l 27% PEG 500 MME and 100 mM Tris 7.5 plus 5 mM MgCl2, followed by a final exchange of this solution plus 5 mM nucleotide. Nucleotides were soaked for ~ 1 day. , VAPOR DIFFUSION, SITTING DROP, temperature 277K
