The first essential condition for nitrogen fixation is the legume-bacteria relationship. The enzymes necessary for nitrogen fixation are present in root nodules and thus enable rhizobium to fix nitrogen. The conversion of nitrogen into ammonia is facilitated by the enzyme nitrogenase which is the first stable product of nitrogen fixation. Ammonia is then converted into glutamic acid. The plants utilize glutamic acid and make amino acids; which are then utilised to make protein.
