The requirement for molybdenum in biological dinitrogen fixation, first reported by Bortels1, is due to its involvement at or near the site of reduction of N2 in conventional nitrogenase. To date, all nitrogenases which have been purified to homogeneity consist of an iron protein (component 2) and a molybdoprotein (component 1)2. Azotobacter vinelandii, an obligately aerobic diazotrophic bacterium, has two systems for nitrogen fixation: a conventional nitrogenase involving molybdenum and an… Expand
