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.80% similarUnverifiedThe carbon-fluorine bond (C—F) is one of the strongest single bonds in organic chemistry, with a bond energy of about 485 kJ/mol, far higher than the carbon-hydrogen bond (about 413 kJ/mol) and the carbon-carbon bond (about 347 kJ/mol).72% similarUnverifiedThree nitrogenase isoforms exist in nature: molybdenum nitrogenase, vanadium nitrogenase, and iron-only nitrogenase, with the latter two having significantly lower catalytic efficiency than molybdenum nitrogenase.65% similarUnverifiedThe nitrogenase-catalyzed reaction requires 16 ATP to fix one N₂ molecule and is extremely sensitive to oxygen.63% similarUnverifiedBiological nitrogenase can convert nitrogen into ammonia at ambient temperature and pressure, and its active center contains an iron-molybdenum-sulfur cluster.62% similar
