Description
The six-subunit complex RnfABCDGE in Rhodobacter capsulatus (Rhodopseudomonas capsulata) encodes an apparent NADH oxidoreductase responsible for electron transport to nitrogenase, necessary for nitrogen fixation
[2]. 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
[1]. Although this family of putative NADH oxidoreductase complexes exists in many of the same species as the related NQR family, a Na(+)-translocating NADH-quinone reductase (
IPR003667), RnfABCDGE is distinct.
