Crystals were obtained by initial screening at 20 degrees Celsius using the sitting drop method on a 96-Well MRC 2-Drop Crystallization Plates in polystyrene (SWISSCI). The crystallization reservoir contained 90 ul of mother liquor, the crystallization drop contained a mixture of 0.6 ul protein at 4.64 mg.ml-1 and 0.6 ul precipitant. The protein was in 25 mM Tris/HCl buffer pH 7.6, 10 % (v/v) glycerol, 2 mM DTT, 1 mM FAD and 1 mM FMN.
The crystal was obtained in a Coy tent under an N2/H2 atmosphere (96:4 %). The crystallization reservoir contained 200 mM sodium acetate trihydrate, 100 mM sodium cacodylate, pH 6.5, and 18 % (w/v) polyethylene glycol 8,000. The crystal was soaked in the crystallization solution supplemented with 30 % (v/v) glycerol before freezing in liquid nitrogen. |
