CC -!- FUNCTION: Component of the hydrazine synthase complex that CC catalyzes the condensation of nitric oxide (NO) with ammonium to CC form hydrazine (PubMed:21964329). The alpha subunit catalyzes the CC second half-reaction, i.e. the condensation of hydroxylamine CC formed in the active site of the gamma subunit with ammonia, CC yielding hydrazine (PubMed:26479033). Is involved in anaerobic CC ammonium oxidation (anammox), a biological process in which CC nitrite is used as the electron acceptor in the conversion of CC ammonium to dinitrogen gas (N2) and water; this bacterial process CC has a major role in the Earth's nitrogen cycle and has been CC estimated to synthesize up to 50% of the dinitrogen gas emitted CC into our atmosphere from the oceans (PubMed:21964329, CC PubMed:26479033). {ECO:0000269|PubMed:21964329, CC ECO:0000269|PubMed:26479033}. CC -!- CATALYTIC ACTIVITY: Hydrazine + H(2)O + 3 ferricytochrome c = CC nitric oxide + ammonium + 3 ferrocytochrome c. CC {ECO:0000269|PubMed:21964329}. CC -!- COFACTOR: CC Name=heme c; Xref=ChEBI:CHEBI:61717; CC Evidence={ECO:0000269|PubMed:26479033}; CC Note=Binds two heme c groups per subunit. CC {ECO:0000269|PubMed:26479033}; CC -!- PATHWAY: Nitrogen metabolism. {ECO:0000269|PubMed:21964329}. CC -!- SUBUNIT: Part of the hydrazine synthase complex that forms an CC elongated dimer of heterotrimers composed of one alpha, one beta CC and one gamma subunit. {ECO:0000269|PubMed:26479033}. CC -!- SUBCELLULAR LOCATION: Anammoxosome {ECO:0000305|PubMed:21964329}. CC -!- INDUCTION: Is among the most highly expressed proteins in the CC proteome. {ECO:0000269|PubMed:21964329}. CC -!- DOMAIN: The alpha subunit consists of three domains: an N-terminal CC domain which includes a six-bladed beta-propeller, a middle domain CC binding a pentacoordinated c-type heme and a C-terminal domain CC which harbors a bis-histidine-coordinated c-type heme.
