Nitrogenase (EC 1.18.6.1) is the enzyme used by some organisms to fix atmospheric nitrogen gas (N2). It is the only known family of enzymes which 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.
