This domain is often found next to the Pfam:PF02254 domain. The exact function of this domain is unknown. It has been suggested that it may bind an unidentified ligand [1]. The domain is predicted to adopt an all beta structure [1].

This family contains phosphate regulatory proteins including PhoU. PhoU proteins are known to play a role in the regulation of phosphate uptake. The PhoU domain is composed of a three helix bundle [1]. The PhoU protein contains two copies of this domain. The domain binds to an iron cluster via its conserved E/DXXXD motif.
