Nitrogenase and homologs. [PDF]
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 catalyzes the enzymatic reduction of atmospheric dinitrogen to ammonia during the process of biological nitrogen fixation. Nitrogenase consists of two component metalloproteins, the iron (Fe-) protein and the molybdenum-iron (MoFe-) protein ...

Crystallization of Nitrogenase Proteins
Nitrogenase is the only known enzymatic system capable of reducing atmospheric dinitrogen to ammonia. This unique reaction requires tightly choreographed interactions between the nitrogenase component proteins, the molybdenum–iron (MoFe)- and iron (Fe ...

Chimeric Interaction of Nitrogenase‐Like Reductases with the MoFe Protein of Nitrogenase
The engineering of transgenic organisms with the ability to fix nitrogen is an attractive possibility. However, oxygen sensitivity of nitrogenase, mainly conferred by the reductase component (NifH)2, is an imminent problem.

The Spectroscopy of Nitrogenases [PDF]
Nitrogenases are responsible for biological nitrogen fixation, a crucial step in the biogeochemical nitrogen cycle. These enzymes utilize a two-component protein system and a series of iron-sulfur clusters to perform this reaction, culminating at the FeMco active site (M = Mo, V, Fe), which is capable of binding and reducing N2 to 2NH3. In this review,

The photoreduction of nitrogenase [PDF]
The photoreduction, without reductant dithionite, of N2 to NH3 or acetylene to ethylene catalysed by nitrogenase in the presence of Mg2+. ATP, eosin and NADH in the light has been established. There is an optimum NADH concentration for each particular eosin concentration.

Metalloclusters of the nitrogenases [PDF]
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 resurrection and the evolution of a singular enzymatic mechanism
The planetary biosphere is powered by a suite of key metabolic innovations that emerged early in the history of life. However, it is unknown whether life has always followed the same set of strategies for performing these critical tasks.

The photosynthetic α‐proteobacterium Rhodobacter capsulatus reduces and thereby fixes atmospheric dinitrogen (N2) by a molybdenum (Mo)‐nitrogenase and an iron‐only (Fe)‐nitrogenase.
