Control of electron transfer in nitrogenase.
The bacterial enzyme nitrogenase achieves the reduction of dinitrogen (N2) to ammonia (NH3) utilizing electrons, protons, and energy from the hydrolysis of ATP. Building on earlier foundational knowledge, recent studies provide molecular-level details on how the energy of ATP hydrolysis is utilized, the sequencing of multiple electron transfer events, and the nature of energy transduction across this large protein complex. Here, we review the state of knowledge about energy transduction in nitrogenase.
