Protein Family Models

This conserved region includes the FMN-binding site of the NqrC protein [1] as well as the NosR and NirI regulatory proteins. This domain is post-translationally flavinylated that may facilitate electron transfer, and thus, resembles multiheme cytochromes [3]. [1]. 11248234.

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.
