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 [1]. FeoB has been identified as part of this transport system. FeoB is a large 700-800 amino acid integral membrane protein. The N terminus contains a P-loop motif suggesting that iron transport may be ATP dependent [1].	Domain
A, B	PF17910	FeoB cytosolic helical domain (FeoB_Cyto)	FeoB cytosolic helical domain	FeoB is a G-protein coupled membrane protein essential for Fe(II) uptake in prokaryotes. In the structures, a canonical G-protein domain (G domain) is followed by a helical bundle domain (S-domain) which is represented by this entry.	Domain
