Interaction of ferredoxin-linked nitrite reductase with ferredoxin
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1985Abstract The native, ferredoxin-linked, form ( M r = 85 000) of nitrite reductase (ferredoxin:nitrite oxidoreductase, EC 1.7.7.1) forms a complex with ferredoxin that can be detected either by enzyme binding to a ferredoxin-Sepharose 4B affinity column or by spectral changes produced when the two proteins are mixed.

Trends in Ecology & Evolution, 1988
Ferredoxins are electron carrier proteins that contain active sites consisting of nonheme iron and inorganic sulfur. They are ubiquitous in living cells and are believed to be among the earliest redox proteins having appeared in primitive organisms. The small size of Ferredoxins allows their amino acid sequences to be determined with relative ease, and

Immobilized ferredoxins for affinity chromatography of ferredoxin-dependent enzymes
Journal of Chromatography A, 1992An immobilized ferredoxin more stable than the conventional immobilized spinach ferrodoxin was prepared by reacting CNBr-Sepharose with ferredoxins isolated from barley and Synechococcus vulcanus, a thermophilic blue-green alga. The dissociation constants of immobilized ferredoxin from spinach, barley and S.

Ferredoxin-thioredoxin reductase: Properties of its complex with ferredoxin
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1988Abstract Ferredoxin-thioredoxin reductase formed an electrostatically stabilized 1:1 complex with ferredoxin. Complex formation could be detected, following mixing of the two proteins, either by changes in optical absorbance and circular dichroism spectra or by co-chromatography during gel filtration.

The Interaction of Ferredoxin with Ferredoxin-Dependent Enzymes
2007Summary Ferredoxin, reduced by Photosystem I (PS I) in the light, serves as the electron donor for the reduction of NADP + to NADPH, of sulfite to sulfide, of nitrite to ammonia and for the reductant-requiring of glutamate and 2-oxoglutarate to glutamate in all oxygenic photosynthetic organisms.

Chemical modification studies have been conducted on spinach ferredoxin to determine the nature of the groups on ferredoxin involved in its interaction with its reaction partners. Modification of a limited number (three or four) carboxyl groups or of the single histidine residue resulted in a decreased ability of ferredoxin to participate in NADP ...

Einflu� von Ferredoxin auf Ferredoxin-NADP-Reduktase
Planta, 1971Transhydrogenase and diaphorase activity of ferredoxin-NADP reductase are enhanced by plant ferredoxins. This stimulation is specific; ferredoxin cannot be replaced by sulfhydryl compounds such as cysteine or dithiothreitol, the apoprotein of ferredoxin or Fe2+, Fe3+ ions.

A competitive Brownian model for the interaction of ferredoxin, ferredoxin NADP+ reductase and hydrogenase has been built. In the model, molecules of three types of proteins are placed into a cubic reaction volume, where they move under Brownian and electrostatic forces created by neighboring molecules and the solution.

Reduction of ferredoxin by photosystem I (PSI) involves the [4Fe-4S] clusters FA and FB harbored by PsaC, with FB being the direct electron transfer partner of ferredoxin (Fd). Binding of the redox-inactive gallium ferredoxin to PSI was investigated by flash-absorption spectroscopy, studying both the P700+ decay and the reduction of the native iron Fd ...

Ferredoxin and Ferredoxin-Dependent Enzymes
1996Ferredoxin, a Mr=11 kDa protein that contains a single low potential [2Fe-2S] cluster, serves as the ultimate acceptor of electrons from Photosystem I. In addition to serving as the electron donor for NADP+ reduction, a reaction catalyzed by the FAD-containing, membrane-associated enzyme ferredoxin: NADP+ oxidoreductase, ferredoxin also serves as the ...
