Graphical Abstract
PuIV complexed by desferrioxamine E (DFE) is nine coordinate with a tricapped trigonal prismatic geometry. The DFE ligand lies in one hemisphere and three water molecules occupy the other (see structure). These and other features of the FeIII and PuIV structures provide insights into the ferrioxamine-like mechanisms used by microorganisms for transporting metals across membranes.
