All crystallization was performed in an anaerobic chamber (95% N2/5% H2) with anoxic solution using the sitting drop method (96-well 2-drop MRC Crystallization Plates in polystyrene, Molecular Dimensions, Suffolk, UK). The crystallization reservoir contained 100 mM Tris/HCl, pH 8.5, 30% (w/v) polyethylene glycol 4000, and 200 mM Na acetate trihydrate. Crystallization drop contained 1 ul HdrABC-MvhAGD at 25 mg/ml premixed with 2 mM FAD and 1 ul of precipitant. The soaking experiment with the bromoethanesulfonate was done by soaking the crystals in the same crystallization solution supplemented with 66 mM of bromoethanesulfonate for 7 min. The crystal has been cryo-protected using the the mother liquor solution supplemented with 30% glycerol and 10 mM bromoethanesulfonate. |
