Structures of the nitrogenase complex prepared under catalytic turnover conditions
Science, 2022 The enzyme nitrogenase couples adenosine triphosphate (ATP) hydrolysis to the multielectron reduction of atmospheric dinitrogen into ammonia. Despite extensive research, the mechanistic details of ATP-dependent energy transduction and dinitrogen ...

FEBS Letters, 2022 Nitrogenase is the sole enzyme responsible for the ATP‐dependent conversion of atmospheric dinitrogen into the bioavailable form of ammonia (NH3), making this protein essential for the maintenance of the nitrogen cycle and thus life itself.

Scientific Reports, 2022 Since nitrogenase is irreversibly inactivated within a few minutes after exposure to oxygen, current studies on the heterologous expression of nitrogenase are limited to anaerobic conditions.

Potential of Phototrophic Purple Nonsulfur Bacteria to Fix Nitrogen in Rice Fields
Microorganisms, 2021 Biological nitrogen fixation catalyzed by Mo-nitrogenase of symbiotic diazotrophs has attracted interest because its potential to supply plant-available nitrogen offers an alternative way of using chemical fertilizers for sustainable agriculture ...

Two ligand-binding sites in CO-reducing V nitrogenase reveal a general mechanistic principle
Science Advances, 2021 A structure of V nitrogenase with two CO ligands outlines a route for C–C coupling in Fischer-Tropsch–like hydrocarbon formation. Besides its role in biological nitrogen fixation, vanadium-containing nitrogenase also reduces carbon monoxide (CO) to ...

Hydrogen Reactions of Nitrogenase [PDF]
Journal of Biological Chemistry, 1968 Abstract HD formation from either D2 and H2O or H2 and D2O is shown to be catalyzed by N2-fixing extracts of Azotobacter vinelandii. The activity parallels nitrogenase but not hydrogenase activity and is not catalyzed by the sites of nitrogenase responsible for either ATP-dependent H2 evolution or competitive inhibition by H2 of N2 fixation ...

Metalloclusters of the nitrogenases [PDF]
European Journal of Biochemistry, 1992 Biological nitrogen fixation, the reduction of dinitrogen to ammonia, is catalysed by nitrogenases. These enzymes are found in relatively few groups of bacteria and until recently it appeared that N2 fixation occurred by a single route involving a molybdenum-containing enzyme.

Nitrogenase and homologs [PDF]
JBIC Journal of Biological Inorganic Chemistry, 2014 Nitrogenase catalyzes biological nitrogen fixation, a key step in the global nitrogen cycle. Three homologous nitrogenases have been identified to date, along with several structural and/or functional homologs of this enzyme that are involved in nitrogenase assembly, bacteriochlorophyll biosynthesis and methanogenic process, respectively.
