[[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>
