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.	Domain
