Purification and structural characterization of the Na+-translocating ferredoxin: NAD+ reductase (Rnf) complex of Clostridium tetanomorphum [PDF]

Nature Communications, 2022
Rnf reversibly reduces NAD+ by ferredoxin coupled with Na+/H+ pumping for microbial ion gradient or reduced ferredoxin formation. Here, a cryo-EM structure provides information about the participating iron and flavin cofactors, the electron transfer ...

Ferredoxin/ferredoxin-thioredoxin reductase complex: Complete NMR mapping of the interaction site on ferredoxin by gallium substitution

FEBS Letters, 2006
The reduction of ferredoxin–thioredoxin reductase (FTR) by plant‐type ferredoxin plays an important role in redox regulation in plants and cyanobacteria. Nuclear magnetic resonance (NMR) was used to map the binding sites on Synechocystis ferredoxin for FTR.

Effect of Artemisinin on the Redox System of NADPH/FNR/Ferredoxin from Malaria Parasites

Antioxidants, 2022
FNR and ferredoxin constitute a redox cascade, which provides reducing power in the plastid of malaria parasites. Recently, mutation of ferredoxin (D97Y) was reported to be strongly related to the parasite’s resistance to the front-line antimalarial drug

Ferredoxin and ferredoxin–heme maquettes [PDF]

Proceedings of the National Academy of Sciences, 1996
A 16-amino acid residue peptide derived from a consensus motif of natural ferredoxins incorporates a tetranuclear iron sulfur cluster under physiological conditions. Successful assembly of the [4Fe–4S] 2+/1+ cluster within a monomeric peptide was demonstrated using size exclusion chromatography, UV-visible ...

Plant type ferredoxins and ferredoxin‐dependent metabolism [PDF]

Plant, Cell & Environment, 2013
Ferredoxin (Fd) are small [Fe‐S] cluster containing proteins, which act as the first soluble acceptors of electrons on the stromal side of the chloroplast electron transport chain. In addition to their primary function in photosynthesis, Fds are also involved in a number of other essential metabolic reactions, including biosynthesis of chlorophyll ...

Evolving a New Electron Transfer Pathway for Nitrogen Fixation Uncovers an Electron Bifurcating-Like Enzyme Involved in Anaerobic Aromatic Compound Degradation

mBio, 2023
Nitrogenase is the key enzyme involved in nitrogen fixation and uses low potential electrons delivered by ferredoxin (Fd) or flavodoxin (Fld) to reduce dinitrogen gas (N2) to produce ammonia, generating hydrogen gas (H2) as an obligate product of this ...

Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria

eLife, 2022
The decarboxylation of pyruvate is a central reaction in the carbon metabolism of all organisms. It is catalyzed by the pyruvate:ferredoxin oxidoreductase (PFOR) and the pyruvate dehydrogenase (PDH) complex.
