Crystals were grown by hanging-drop vapor diffusion at 23C for one week using a 2uL:2uL mixture of protein solution (8 mg/ml in 50 mM Tris 7.5, 0.5 M NaCl, 10% glycerol, 1 mM DTT) and precipitant buffer (100 mM Tris 8.0, 3.2 M ammonium formate, 0.3% octyl-beta-glucoside (w/v), 3.2% 2-butanol (v/v)) in Easy-Xtal trays. Crystals were soaked in 1mM DTT (in precipitant buffer) for 15 minutes, then soaked in CuCl2 (in precipitant buffer) for 30 minutes, and finally, backsoaked and cryoprotected in 20% glycerol (in precipitant buffer). |
