1VAPOR DIFFUSION, SITTING DROP9.1288Purified enzyme (3.25 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 0.182 mM CABP and 2.9 mM MgCl2. The enzyme was then mixed in a 1:1 ratio with 0.2 M Bis-Tris propane, 20 % (w/v) polyethylene glycol 4000, pH 9.1. Before flash freezing the crystals in liquid nitrogen PEG200 was added to the mother liquor as cryoprotectant to a final concentration of 33 % (w/v).
