1. Nitrogenase

   Nitrogenases are enzymes (EC 1.18.6.1EC 1.19.6.1) that are produced by certain bacteria, such as cyanobacteria (blue-green bacteria) and rhizobacteria. These enzymes are responsible for the reduction of nitrogen (N2) to ammonia (NH3). Nitrogenases are the only family of enzymes known to catalyze this reaction, which is a key step in the process of nitrogen fixation. Nitrogen fixation is required for all forms of life, with nitrogen being essential for the biosynthesis of molecules (nucleotides, amino acids) that create plants, animals and other organisms. They are encoded by the Nif genes or homologs. They are related to protochlorophyllide reductase.

1. nitrogenase

   Nitrogenase is a specialized enzyme that is responsible for the conversion of atmospheric nitrogen into ammonia, a form that is usable by plants. This process, known as nitrogen fixation, is a critical part of the nitrogen cycle. Nitrogenase is found in certain bacteria and archaea, including those that form symbiotic relationships with plants.

1. Nitrogenase

   Nitrogenases are enzymes used by some organisms to fix atmospheric nitrogen gas. There is only one known family of enzymes that accomplishes this process. Dinitrogen is quite inert because of the strength of its N≡N triple bond. To break one nitrogen atom away from another requires breaking all three of these chemical bonds. Whilst the equilibrium formation of ammonia from molecular hydrogen and nitrogen has an overall negative enthalpy of reaction, the energy barrier to activation is very high without the assistance of catalysis. In addition to reducing agents, such as dithionite in vitro, or ferredoxin or flavodoxin in vivo, the enzymatic reduction of dinitrogen to ammonia therefore also requires an input of chemical energy, released from the hydrolysis of ATP, to overcome the activation energy barrier. The enzyme is composed of the heterotetrameric MoFe protein that is transiently associated with the homodimeric Fe protein. Electrons for the reduction of nitrogen are supplied to nitrogenase when it associates with the reduced, nucleotide-bound homodimeric Fe protein. The heterocomplex undergoes cycles of association and disassociation to transfer one electron, which is the rate-limiting step in nitrogen reduction. ATP supplies the energy to drive the transfer of electrons from the Fe protein to the MoFe protein. The reduction potential of each electron transferred to the MoFe protein is sufficient to break one of dinitrogen's chemical bonds, though it has not yet been shown that exactly three cycles are sufficient to convert one molecule of N2 to ammonia. Nitrogenase ultimately bonds each atom of nitrogen to three hydrogen atoms to form ammonia, which is in turn bonded to glutamate to form glutamine. The nitrogenase reaction additionally produces molecular hydrogen as a side product.
