Angew.Chem.Int.Ed.Engl., 52:4595-, 2013 Cited by PubMed Abstract: Iron-bound structure: The ferric complex of a tetradentate siderophore mimic was synthesized and co-crystallized with the periplasmic binding protein CeuE of Campylobacter jejuni. In addition to electrostatic and hydrogen-bonding interactions between the binding pocket and the substrate, the structure showed direct coordination of two amino acid side chains to the Fe(III) center (orange, see figure).
