Nitrogen fixation and nitrogenase activity of Azotobacter chroococcum
The purpose of the present investigation was to study the effect of some chemical, physical and biological factors on growth, efficiency of nitrogen fixation and nitrogenase activity of Azotobacter chroococcum.From biochemical studies with cell-free ...

Directed evolution of nitrogenase
Nitrogen-fixation, which converts gaseous nitrogen (N2) into bioavailable ammonia (NH3) is a critically important reaction in the biosphere. Industrial nitrogen-fixation is an energy- intensive chemical reaction that produces NH3-based fertilisers ...

Aerobic nitrogen fixation in Azotobacter vinelandii
I ELECTRON DONATION TO NITROGENASEPaper I shows that the hypothesis, that a high ratio of (NADH + NADPH) / (NAD + + NADP + ) is the source of reducing power for nitrogenase in intact A.vinelandii, is invalid.

Structure and Function of Nitrogenase
This chapter discusses the structures of the metal centers and polypeptide chains of the nitrogenase proteins based on the crystallographic structures of both the Fe-protein and the MoFe protein that have been determined at Caltech.

GmDOF3.1‐GmCPX Module Regulates Nodulation and Nitrogen Fixation Abilities in Soybean
ABSTRACT Soybean nodule nitrogen fixation is very important, which can provide a large amount of nitrogen supply for its own growth and that of other crops, but the mechanism is largely unclear. In the present study, a coproporphyrinogen oxidase gene, GmCPX, was identified to facilitate soybean nodulation and nitrogen‐fixation under the regulation of ...

Reduction of Substrates by Nitrogenases
Nitrogenase is the enzyme that catalyzes biological N2 reduction to NH3. This enzyme achieves an impressive rate enhancement over the uncatalyzed reaction. Given the high demand for N2 fixation to support food and chemical production and the heavy reliance of the industrial Haber-Bosch nitrogen fixation reaction on fossil fuels, there is a strong need ...

Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Effect of combined nitrogen on symbiotic nitrogen fixation in pea plants
The nitrogen-fixing activity of the symbiotic system of Pisum sativum with Rhizobium leguminosarum is adversely affected by combined nitrogen. Both ammonium chloride and potassium nitrate, when added to the roots, lower the nitrogenase activity ...

ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...
