Protein Family Models

This is a family of integral membrane proteins including Rhodobacter-specific nitrogen fixation (rnf) proteins RnfA and RnfE [1] and Na+-translocating NADH:ubiquinone oxidoreductase (Na+-NQR) subunits NqrD and NqrE.

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 E. 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 model describes the A subunit.

electron transport complex subunit A is a component of a membrane complex involved in functions such as maintaining the reduced state of SoxR (RsxA) or transfering electrons to nitrogenase (RnfA)
