Abstract:
The prokaryotic ferritin gene of Campylobacter jejuni was overexpressed in Escherichia coli under control of the bacteriophage T7 promoter and the protein (Cj-FTN) purified. Preliminary crystallization experiments have been performed using the hanging-drop vapour-diffusion method with ammonium sulfate as the precipitant. Diffraction studies show the crystals belong to the I432 space group (a = 151.52 A). Structure solution by molecular replacement is in progress while crystal quality improvement is carried out.
