Nitrogen Fixation in Bacteria and Higher Plants

Our knowledge of the biochemistry and biophysics of dinitrogen fixa­ tion has developed rapidly in the 15 years since the first N2-fixing enzyme system was successfully extracted from a bacterium. This peri­ od has produced a literature that now describes the N2 fixation reac­ tion and the nitrogenase enzyme itself in sophisticated terms, though a detailed reaction mechanism at the chemical level ...
