Ion-translocating oxidoreductase complex, subunit RnfC/RsxC (IPR010208)

Short name: Ion_transpt_RnfC/RsxC

Overlapping homologous superfamilies


Family relationships



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 [PMID: 8264535, PMID: 9492268, PMID: 10671439]. 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 [PMID: 12773378]. This family of putative NADH oxidoreductase complexes exists in many of the same species as the related NQR, a Na(+)-translocating NADH-quinone reductase (IPR003667), but is distinct. This entry describes the C subunit.
