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 ...

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 ...

Food and Energy Security, 2023 Soybean is a rich source of protein and oil for humans. It forms a symbiotic association with rhizobia to fix atmospheric nitrogen for its growth and development. Rhizobial type‐III effectors act as important signaling molecules in symbiosis.

Nitrogen Fixation and Hydrogen Evolution by Sterically Encumbered Mo-Nitrogenase
, 2023 The substrate-reducing proteins of all nitrogenases (MoFe, VFe, and FeFe) are organized as α2ß2(γ2) multimers with two functional halves. While their dimeric organization could afford improved structural stability of nitrogenases in vivo, previous ...

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2013 Nitrogenase contains two unique metalloclusters: the P-cluster and the M-cluster. The assembly processes of P- and M-clusters are arguably the most complicated processes in bioinorganic chemistry. There is considerable interest in decoding the biosynthetic mechanisms of the P- and M-clusters, because these clusters are not only biologically important ...

Classifying the metal dependence of uncharacterized nitrogenases
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.

Scientific Reports, 2022 Biological nitrogen fixation (BNF) is the reduction of N2 into NH3 in a group of prokaryotes by an extremely O2-sensitive protein complex called nitrogenase. Transfer of the BNF pathway directly into plants, rather than by association with microorganisms,

Archaea, bacteria and termite, nitrogen fixation and sustainable plants production
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021 Certain bacteria and archaea are responsible for biological nitrogen fixation. Metabolic pathways usually are common between archaea and bacteria. Diazotrophs are categorized into two main groups namely: root-nodule bacteria and plant growth-promoting ...

Nitrogenase-Relevant Reactivity of a Synthetic Iron–Sulfur–Carbon Site
, 2019 Simple synthetic compounds with only S and C donors offer a ligation environment similar to the active site of nitrogenase (FeMoco) and thus demonstrate reasonable mechanisms and geometries for N2 binding and reduction in nature. We recently reported the
