Crystallization was performed anaerobically by initial screening at 20 degrees Celsius using the sitting drop method on 96 Well MRC 2 Drop polystyrene Crystallization Plates SWISSCI in a Coy tent containing an N2/H2 (97:3%) atmosphere. The reservoir contained 90 ul of 25 % (w/v) glycerol ethoxylate 1,000, 100 mM Tris/HCl pH 8.5, and 100 mM CaCl2. 0.6 ul of crystallization solution was mixed with 0.6 ul of the protein, containing a final concentration of 2 mM acetyl-CoA. The protein was concentrated at 15 mg/ml in 25 mM Tris/HCl pH 7.6, 10% (v/v) glycerol, and 2 mM dithiothreitol.
The crystals appeared in few weeks and were soaked in the crystallization solution supplemented with 15% (v/v) Ethylene glycol for a few seconds before freezing in liquid nitrogen. |
