Nitrogenase Enzyme

Fe7MoS9C center (FeMo-cofactor) contains the active site of nitrogen fixation responsible for the Nitrogen (N₂) reduction into Ammonia (NH₃).

A simple modification in the secondary coordination sphere (amino acids) of the FeMo-co can transform Carbon dioxide (CO₂) into Methane (CH₄).
