Most enzymes catalyze reactions at ambient temperature and pressure.
These qualities are of great interest when developing new catalysts for organic reactions. Studying enzyme mechanism on the molecular level leads to an in-depth understanding of how evolution uses the principles of chemistry and physics to direct, enhance and control biological processes. Additionally, understanding how enzymes work can lead to development of new drugs of medical importance, new paths in organic synthesis, and new methodologies in biotechnology. These are small proteins that catalyze hydrogen transfer by many orders of magnitude and are of great medical interest. The mechanism of dinitrogen reduction by nitrogenases.
