DESCRIPTION

Also known as NRFH_DESVH, DVU_0624. 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). Component of the NrfHA cytochrome c nitrite reductase complex composed of 4 NrfA catalytic subunits and 2 NrfH quinone-binding subunits (PubMed:17139260, PubMed:18597779, PubMed:22519292). Interacts with NrfA homodimer (PubMed:16754983, PubMed:17139260).
