== Function ==
 +
[https://www.uniprot.org/uniprot/FHUA_ECOLI FHUA_ECOLI] This receptor binds the ferrichrome-iron ligand. It interacts with the TonB protein, which is responsible for energy coupling of the ferrichrome-promoted iron transport system. Acts as a receptor for bacteriophage T5 as well as T1, phi80 and colicin M. Binding of T5 triggers the opening of a high conductance ion channel. Can also transport the antibiotic albomycin.<ref>PMID:8617231</ref>

== Publication Abstract from PubMed ==
 +
FhuA, the receptor for ferrichrome-iron in Escherichia coli, is a member of a family of integral outer membrane proteins, which, together with the energy-transducing protein TonB, mediate the active transport of ferric siderophores across the outer membrane of Gram-negative bacteria. The three-dimensional structure of FhuA is presented here in two conformations: with and without ferrichrome-iron at resolutions of 2.7 and 2.5 angstroms, respectively. FhuA is a beta barrel composed of 22 antiparallel beta strands. In contrast to the typical trimeric arrangement found in porins, FhuA is monomeric. Located within the beta barrel is a structurally distinct domain, the "cork," which mainly consists of a four-stranded beta sheet and four short alpha helices. A single lipopolysaccharide molecule is noncovalently associated with the membrane-embedded region of the protein. Upon binding of ferrichrome-iron, conformational changes are transduced to the periplasmic pocket of FhuA, signaling the ligand-loaded status of the receptor. Sequence homologies and mutagenesis data are used to propose a structural mechanism for TonB-dependent siderophore-mediated transport across the outer membrane.
