Crystals were grown by mixing an equal volume of the protein solution with 8-12% PEG 4000, 0.1 M Morpheus buffer system 1 (MES/imidazole) pH 7, 100 mM KCl, 20 v/v % glycerol. For soaking a 4 mM solution of compound in DMSO was used. A one third volume of the initial drop size was pipetted carefully onto the crystal containing drop. The sample was then placed back over the reservoir and incubated for approximately 2 hr. Crystals were caught in cryoloops and directly flash frozen in liquid nitrogen. |
