Interaction of ferredoxin and ferredoxin-NADP reductase with thylakoids
Archives of Biochemistry and Biophysics, 1983Ferredoxin-NADP reductase accounts for about 50% of the NADPH diaphorase activity of spinach leaf homogenates. The enzyme is bound to thylakoid membranes, but can be slowly extracted by aqueous buffers. Ferredoxin-NADP reductase can be extracted from the membranes by a 1- to 2-min treatment with a low concentration of trypsin. This treatment completely

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.

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.

Ferredoxin and Photosynthetic Phosphorylation
Nature, 1967The iron-bearing protein ferredoxin is present in all photosynthetlc cells. It has now been shown that ferredoxin can catalyse, by two distinct photochemical reactions, the production of ATP in cell-free photosynthetic systems at rates comparable with the maximum rates of photosynthesis in vivo.

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 ...

The reconstitution of clostridial ferredoxin
Biochemical and Biophysical Research Communications, 1966Previous experiments from this laboratory (Lovenberg, et al., 1963; Malkin & Rabinowitz, 1966) indicated that when bacterial ferredoxin is treated with a mercurial, the color of the protein is bleached, and both the iron and the acidlabile sulfide of the protein are released.

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 ...

Complex formation by ferredoxin-NADP+ reductase with ferredoxin or NADP+
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1973Abstract Complex formation by ferredoxin-NADP + reductase (NADPH:ferredoxin oxidoreductase, EC 1.6.99.4) with ferredoxin was measured by the independent methods based on the changes of circular dichroism, fluorescence intensity and the chromatographic behavior on a Sephadex G-75 column of the two proteins after mixing.

Biophysics, 2016
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.
