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.

Ferredoxin from Veillonella alcalescens
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973Abstract Ferredoxin from Veillonella alcalescens was isolated and purified giving an A 390 A 280 ratio of 0.82. Amino acid assays, iron and acid-labile sulfide analysis and EPR measurements indicate that the protein belongs to the class of eight iron-eight acid-labile sulfide ferredoxins.

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.

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 ...

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

[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 ...

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 from Bacillus Stearothermophilus
1976Ferredoxins are low molecular weight electron transfer proteins found in all types of living organisms (1–3). They are used in many reactions ocurring at low redox potentials. The active centre of the ferredoxins consists of a chromophore containing iron and labile sulphur atoms.
