This family includes FeoA a small protein, probably involved in Fe2+ transport [1]. This presumed short domain is also found at the C-terminus of a variety of metal dependent transcriptional regulators. This suggests that this domain may be metal-binding. In most cases this is likely to be either iron or manganese.	Domain
