Figure 4
Stereodiagram of the active site of the rkbPAP-fluoride complex. Fo-Fc electron density for the bridge is overlayed. The fluoride replaces the hydroxide in the bridging position. General legend: Fe(III) is in tan, Zn(II) in grey, sodium in purple, fluoride in cyan, carbon in green, oxygen in red, nitrogen in blue and sulphur in orange. Hydrogen bonds and other contacts are shown as dashed lines.
