The complex was concentrated using an Amicon Ultra concentrator to around 10 mg/ml and 2 mM AMPPNP (adenosine 5prime-(beta,gamma-imido)triphosphate lithium salt hydrate) was added. Sample and reservoir buffer (0.025 M Bis-Tris pH 6.5, 0.075 M succinic acid pH 7.0, 12-14% PEG 3350, 2% sucrose) were mixed in a 2:1 ratio. Three hours after setup, cover glasses with drops were transferred from a reservoir containing 12-14% PEG 3350 to one containing 8% PEG 3350. Crystals grew in one week at 20 C and were harvested in cryo-protectant solution (0.025 M Bis-Tris pH 6.5, 0.075 M succinic acid pH 7.0, 25% 3350, 10% ethylene glycol) before flash freezing with liquid nitrogen. |
