UnverifiedNitrogenase is the only known enzyme system in nature capable of breaking the triple bond of the N₂ molecule (with a bond energy as high as 945 kJ/mol) under ambient temperature and pressure, and it is composed of two components: iron protein and molybdenum-iron protein.74% similarUnverifiedNitrogenase cleaves the triple bond of N₂, which has a bond energy as high as 945 kJ/mol, making it one of the strongest covalent bonds in nature, and nitrogenase is extremely sensitive to oxygen.65% similar
