Cytochrome c nitrite reductase subunit NrfH

UniProtKB accession:  Q72EF4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Electron donor subunit of the cytochrome c nitrite reductase holocomplex NrfHA. Acquires electrons from the menaquinone pool and mediates their transfer to the catalytic subunit NrfA in an anaerobic respiratory process of nitrite (PubMed:11004582, PubMed:17139260, PubMed:18597779). The other biological function of the NrfHA holocomplex is to detoxify nitrite (PubMed:15547266, PubMed:25534748). This function is essential for the survival of this organism as it enables it to overcome inhibition by nitrite, which is produced by other organisms living in the same environment (Probable).
