Web1 apr. 2004 · Symbiotic nitrogen fixation by the legume‐Rhizobium symbiosis is a finely regulated process that involves significant carbon and energy metabolism by the plant. At present, there are three competing theories as to how the regulation of the process is achieved at the whole plant level. Theory one (carbon supply regulation) states that …
WebNitrogenase, the enzyme that fixes nitrogen, is inactivated by oxygen, so the nodule provides an oxygen-free area for nitrogen fixation to take place. The oxygen is … WebThe nif regulon contains factors, which have the potential to turn on, and off the production of proteins needed for nitrogen fixation according to the conditions that it may find suitable. In addition to the nitrogenase enzyme, the nif genes also encode several regulatory proteins involved in nitrogen fixation.
