Hydrazine synthase subunit gamma

UniProtKB accession:  Q1Q0T3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the hydrazine synthase complex that catalyzes the condensation of nitric oxide (NO) with ammonium to form hydrazine (PubMed:21964329). The gamma subunit catalyzes the first half-reaction, i.e. the three-electron reduction of nitric oxide to hydroxylamine; it may obtain electrons from the triheme cytochrome c kuste2854 (PubMed:26479033). Is involved in anaerobic ammonium oxidation (anammox), a biological process in which nitrite is used as the electron acceptor in the conversion of ammonium to dinitrogen gas (N2) and water; this bacterial process has a major role in the Earth's nitrogen cycle and has been estimated to synthesize up to 50% of the dinitrogen gas emitted into our atmosphere from the oceans (PubMed:21964329, PubMed:26479033).
