MIT chemists have determined the structu yeezy 500 re of the complex that forms when gaseous dinitrogen, or N2, binds to an iron-sulfur cluster, offering clues as to how microbes (in yellow) use nitrogenases to break the nitrogen-nitrogen bond (in pink and green).

However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented industrial processes for ammonia synthesis, almost all ammonia on the planet was generated by microbes using nitrogenases, the only enzymes that can break the nitrogen-nitrogen bond found in gaseous dinitrogen, or N2.These enzymes contain clusters of metal and sulfur atoms that help perform this critical reaction, but the mechanism of how they do so is not well-understood.
