Frontiers in Microbiology, 2018 Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

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 ...

Ferredoxin containing bacteriocins suggest a novel mechanism of iron uptake in Pectobacterium spp. [PDF]
PLoS ONE, 2012 In order to kill competing strains of the same or closely related bacterial species, many bacteria produce potent narrow-spectrum protein antibiotics known as bacteriocins. Two sequenced strains of the phytopathogenic bacterium Pectobacterium carotovorum

Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria [PDF]
bioRxiv, 2021 The decarboxylation of pyruvate is a central reaction in the carbon metabolism of all organisms. Both the pyruvate:ferredoxin oxidoreductase (PFOR) and the pyruvate dehydrogenase (PDH) complex catalyze this reaction.

The Bidirectional NiFe-hydrogenase in Synechocystis sp. PCC 6803 Is Reduced by Flavodoxin and Ferredoxin and Is Essential under Mixotrophic, Nitrate-limiting Conditions* [PDF]
Journal of Biological Chemistry, 2013 Background: Cyanobacterial hydrogenases are claimed to produce hydrogen via NAD(P)H, which contradicts thermodynamic considerations; the physiological function of these hydrogenases is unresolved.

Salutary Effects of Overexpression of Rsm22, an Assembly Factor for the Mitochondrial Ribosome, on Frataxin/Yfh1 Depletion Phenotypes in Saccharomyces cerevisiae [PDF]
BiomoleculesFrataxin is a component of the iron–sulfur (Fe-S) cluster assembly complex in mitochondria, and deficiency is associated with Friedreich ataxia (FA). The yeast homolog Yfh1 resembles and cross-complements with its human equivalent, and frataxin bypass ...

Ferredoxin Gene Mutation in Iranian Trichomonas vaginalis Isolates
Iranian Journal of Parasitology, 2013 Background: Trichomonas vaginalis causes trichomoniasis and metronidazole is its chosen drug for treatment. Ferredoxin has role in electron transport and carbohydrate metabolism and the conversion of an inactive form of metronidazole (CO) to its active ...

Carboxydotrophic Acetogenesis in Alkaline Conditions Results in Transient Formate Production by the Halo‐Alkaliphilic Acetogen Haloacetibacter carboxydivorans Gen. Nov. sp. Nov [PDF]
Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.This work presents the physiological exploration of the halo‐alkaliphilic, carboxydotrophic acetogen bacterium MD4. In contrast to well‐characterised neutrophilic and slightly acidophilic acetogenic carboxydotrophs, this work shows an important role for formate production, instead of ethanol, as a redox exhaust mechanism in alkaline conditions ...
