Figure 3
Superposition of the three Gst structures in ribbon format: apo protein (ice blue), azotochelin complex (gold) and iron(III)-5-LICAM complex (coral). Iron(III)-5-LICAM is shown in ball-and-stick representation coloured by atom type, with the iron-chelating residues as cylinders (azotochelin is not shown to simplify the view but superimposes closely on 5-LICAM). Tyr279 and His218 are shown in green for the apo protein; His218 is very close to its position in the ligand complexes.
