This domain is found in several bacterial Na(+)-translocating NADH-quinone reductase subunit A (NqrA) proteins. The Na(+)-translocating NADH: ubiquinone oxidoreductase (Na(+)-NQR) generates an electrochemical Na(+) potential driven by aerobic respiration [1]. This domain has an alpha/beta structure and binds an FMN cofactor [2].	Domain
