LITERATURE
hanging-drop vapour-diffusion technique at 20°C under several acidic conditions with polyethylene glycol and ammonium sulfate as precipitants. Optimization of the initial crystallizations conditions yields single crystals in solution containing 0.1 M sodium acetate pH 4.6, 18%(w/v) PEG 4000, 0.2 M ammonium sulfate and 15%(v/v) glycerol. An X-ray diffraction data set is collected to a resolution of 2.8 A
