The ODP (Oxygen-binding Di-iron Protein) domain is a distinct member of the metallo-beta-lactamase superfamily recruited to various bacterial and archaeal signal transduction pathways, including chemotaxis, to function as oxygen and iron sensors (1). ODP was shown to act as a sensor for chemotactic responses to both iron and oxygen in the human pathogen Treponema denticola (Td). The ODP di-iron site binds oxygen at high affinity to reversibly form an unusually stable peroxo adduct.	Domain
