Ferrous iron transport protein B, C-terminal (IPR011640)

Short name: Fe2_transport_prot_B_C

Overlapping homologous superfamilies


Domain relationships



Escherichia coli has an iron(II) transport system (feo) which may make an important contribution to the iron supply of the cell under anaerobic conditions [PMID: 8407793]. FeoB has been identified as part of this transport system. FeoB is a large 700-800 amino acid integral membrane protein. The N terminus has been previously erroneously described as being ATP-binding [PMID: 8407793]. Recent work shows that it is similar to eukaryotic G-proteins and that it is a GTPase [PMID: 12446835].
