Function

[HDH_KUEST] Catalyzes the four-electron oxidation of hydrazine to N2 (PubMed:21964329). The electrons derived from hydrazine oxidation may be transferred to the quinone pool and exploited to promote the generation of proton-motive force (pmf) across the anammoxosome membrane (PubMed:21964329, PubMed:23210799). 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). Cannot oxidize hydroxylamine to NO (PubMed:21964329).[1] [2]
