Classifying the metal dependence of uncharacterized nitrogenases [PDF]
Frontiers in Microbiology, 2013 Nitrogenase enzymes have evolved complex iron-sulfur (Fe-S) containing cofactors that most commonly contain molybdenum (MoFe, Nif) as a heterometal but also exist as vanadium (VFe, Vnf) and heterometal independent (Fe-only, Anf) forms.

Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling. [PDF]
Protein SciAbstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...

Unlocking nitrogen regulation: structural insights into the NifL-NifA complex and prospects for engineered diazotrophs. [PDF]
FEBS JThe urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as

Selenocyanate derived Se-incorporation into the nitrogenase Fe protein cluster
eLife, 2022 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 ...

Nitrogenase resurrection and the evolution of a singular enzymatic mechanism
eLife, 2023 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.

Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]
, 2013 The biological reduction of N2 to NH3 catalyzed by Mo-dependent nitrogenase requires at least eight rounds of a complex cycle of events associated with ATP-driven electron transfer (ET) from the Fe protein to the catalytic MoFe protein, with each ET ...

An alternative path for the evolution of biological nitrogen fixation
Frontiers in Microbiology, 2011 Nitrogenase catalyzed nitrogen fixation is the process by which life converts dinitrogen gas into fixed nitrogen in the form of bioavailable ammonia. The most common form of nitrogenase today requires a complex metal cluster containing molybdenum (Mo ...
