Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.7	298	ATCase holoenzyme was crystallized by microdialysis, using 50 L wells. The enzyme solution, at ~18 mg/mL, was dialyzed against a solution of 40 mM citric acid, 3 mM sodium azide, 1 mM 2-mercaptoethanol, 1 mM cytidine 5 -triphosphate, 0.2 mM EDTA (pH 5.7), MICRODIALYSIS, temperature 298K
