X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6.5	288	Purified enzyme (5 mg/mL) in 25 mM Tricine-NaOH, 75 mM NaCl, pH 8.0 was incubated at 3% (v/v) CO2 in air and 30 degrees C for 1 h in the presence of 0.2 mM CABP and 3.2 mM MgCl2. The enzyme was then mixed in a 1:1 ratio with 0.1 M ammonium sulfate, 0.3 M sodium formate, 0.1 M sodium cacodylate , 3% (w/v) gamma-PGA, and 2% (w/v) PEG 3350, pH 6.5. Before flash freezing the crystals in liquid nitrogen PEG200 was added to the mother liquor as cryoprotectant to a final concentration of 40 % (w/v).
