HHsearch alignment for GI: 254780861 and conserved domain: TIGR01944

>TIGR01944 rnfB electron transport complex, RnfABCDGE type, B subunit; InterPro: IPR010207 The six subunit complex RnfABCDGE in Rhodobacter capsulatus encodes an apparent NADH oxidoreductase responsible for electron transport to nitrogenase, necessary for nitrogen fixation. A closely related complex in Escherichia coli, RsxABCDGE (Reducer of SoxR), reduces the 2Fe-2S-containing superoxide sensor SoxR, active as a transcription factor when oxidized. This family of putative NADH oxidoreductase complexes exists in many of the same species as the related NQR, a Na(+)-translocating NADH-quinone reductase, but is distinct. This entry describes the B subunit.; GO: 0009055 electron carrier activity, 0051536 iron-sulfur cluster binding, 0006118 electron transport.
