摘要:
The first completely characterized model for the nitrogenase catalyzed 'N-2 dependent HD formation' from D-2 and protons is described. This key reaction of nitrogenases is most plausibly rationalized by the 'open-side' FeMoco model, which enables us to explain the severe constraints imposed on the N-2 dependent HD formation as well as the noncompetitive inhibition of N-2 fixation by CO.
