Electronic landscape of the P-cluster of nitrogenase as revealed through many-electron quantum wavefunctions [PDF]
The electronic structure of the nitrogenase metal cofactors is central to nitrogen fixation. However, the P-cluster and iron molybdenum cofactor, each containing eight irons, have resisted detailed characterization of their electronic properties. Through

Active Space Pair 2-Electron Reduced Density Matrix Theory for Strong Correlation [PDF]
An active space variational calculation of the 2-electron reduced density matrix (2-RDM) is derived and implemented where the active orbitals are correlated within the pair approximation.

Hydrogen Reactions of Nitrogenase [PDF]
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 ...

Nitrogenase is a complicated enzyme that actives the ATP-dependent reduction of dinitrogen (N2) to ammonia (NH3). The aim of this manuscript is to review the nitrogenase evolution with considering nitrogenase, structure of nitrogenase, action mechanism of nitrogenase and oxygen sensitive mechanism of nitrogenase.

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii
Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering

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.

Nitrogenase Fe Protein: A Multi-Tasking Player in Substrate Reduction and Metallocluster Assembly
The Fe protein of nitrogenase plays multiple roles in substrate reduction and metallocluster assembly. Best known for its function to transfer electrons to its catalytic partner during nitrogenase catalysis, the Fe protein is also a key player in the ...

Selenocyanate derived Se-incorporation into the nitrogenase Fe protein cluster
The nitrogenase Fe protein mediates ATP-dependent electron transfer to the nitrogenase MoFe protein during nitrogen fixation, in addition to catalyzing MoFe protein-independent substrate (CO2) reduction and facilitating MoFe protein metallocluster ...
