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 0.55 ul protein at 8.6 mg.ml-1 and 0.55 ul precipitant. The protein was in 25 mM Tris/HCl buffer pH 7.6, 10 % (v/v) glycerol, and 2 mM dithiothreitol.
The crystal was obtained in a Coy tent under an N2/H2 atmosphere (96:4 %). The crystallization reservoir contained 25% (w/v) PEG 3350, 100 mM BIS-Tris pH 6.5, 200 mM Magnesium chloride hexahydrate. The crystal was soaked in the crystallization solution supplemented with 25 % (v/v) glycerol before freezing in liquid nitrogen. |
