[[http://www.uniprot.org/uniprot/NIFD_AZOVI NIFD_AZOVI]] This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation. [[http://www.uniprot.org/uniprot/NIFH1_AZOVI NIFH1_AZOVI]] The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein (component 2) and a component 1 which is either a molybdenum-iron protein, a vanadium-iron, or an iron-iron protein.[HAMAP-Rule:MF_00533] [[http://www.uniprot.org/uniprot/NIFK_AZOVI NIFK_AZOVI]] This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation.
