Abstract:
Crystal structures have been solved for two bacterial outer membrane proteins, FhuA and FepA, which mediate active transport of chelated iron. Analysis of ligand-induced changes in the structure of FhuA has provided our first structural insights into an active transport mechanism for a complex solute.
