Nitrogenase: Reduction of N2


Picture
The availability of the element N is essential to all life.  We are working to reveal the mechanism for how the bacterial enzyme nitrogenase achieves the conversion of dinitrogen (N2) in air to the usable molecule ammonia (NH3). One goal of our research is to understand how N2 binds and is reduced to NH3.  Recent progress has revealed a central role for metal-hydrides bound to the active site metal cluster called FeMo-cofactor.  

Nitrogenase: Electron Transfer and ATP

 Another aspect of our research is to understand how electrons flow to nitrogenase and the roles of ATP hydrolysis in the mechanism.  Recent progress has established the order of electron transfer and ATP hydrolysis and developed methods for delivery of electrons using light driven nano materials and electrodes.
