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.

Ferredoxin : NADP+ Oxidoreductase
2018Ferredoxin-NADP + reductase, the essential catalyst of NADP + photoreduction, is a flavoprotein ubiquitous in photosynthetic eukaryotic cells and Cyano-bacteria. The cyanobacteria enzyme has a much lower content of methionine and lysine and more histidines.

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.

Properties of ferredoxin reductase and ferredoxin from the bovine corpus luteum
International Journal of Biochemistry, 1984Ferredoxin reductase and ferredoxin were purified from the bovine corpus luteum and their properties compared to the corresponding adrenal proteins. The luteal and adrenal proteins had similar absorbance spectra and molecular weights. Evidence was obtained from spectrophotometric titrations for formation of 1:1 complexes between luteal ferredoxin ...

Anthracycline antibiotic reduction by spinach ferredoxin-NADP+ reductase and ferredoxin
Biochemistry, 1985Spinach NADPH:ferredoxin oxidoreductase (EC 1.6.7.1) catalyzes the NADPH-dependent reduction of the anthracyclines daunomycin, aclacinomycin A, and nogalamycin and their respective 7-deoxyanthracyclinones. Under anaerobic conditions, the endogenous rate of O2 reduction by NADPH catalyzed by ferredoxin reductase (0.12 s-1 at pH 7.4) is augmented by the ...

Interaction between ferredoxin and ferredoxin-NADP reductase from chloroplasts
Biochemical and Biophysical Research Communications, 1968Abstract The photochemical reduction of pyridine nucleotides in isolated chloroplasts was shown to proceed via ferredoxin and ferredoxin-NADP reductase ( Shin et , al. , 1963 . The latter enzyme is a flavoprotein which can also mediate the transfer of electrons in reverse, from NADPH to ferredoxin (Lazzarini and San Pietro, 1962) , or to ...

Archives of Biochemistry and Biophysics, 1986
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 ...

[Influence of ferredoxin on ferredoxin-NADP reductase].
Planta, 2014Transhydrogenase 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 Fe(2+), Fe(3+) ions.The effect is particularly obvious with the reductase from the heterokont ...
