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.

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 ...

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 ...

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 ...

Ferredoxin-nitrite reductase from spinach
Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966Summary 1. Nitrite reductase from a crude homogenate of spinach leaves has been purified about 500-fold and freed from NADP-reductase (EC 1.6.99.4) and nitrate reductase (EC 1.6.6.2). The enzyme, which does not seem to be a flavoprotein, catalyzes the reduction of nitrite to ammonia with a variety of enzyme systems as electron donors and requires

Structure-function relations for ferredoxin reductase
Journal of Bioenergetics and Biomembranes, 1994Ferredoxin: NADP+ reductase is representative of a large family of flavoenzymes which catalyze the interchange of reducing equivalents between one-electron carriers and the two-electron-carrying nicotinamide dinucleotides. The structure of the enzyme from spinach is known at 1.7 A resolution and this structure, together with results of chemical ...

Abstract The behavior of two ferredoxin-dependent enzymes—nitrate reductase and NADP reductase—from Anacystis nidulans on a ferredoxin-Sepharose gel was examined. The oxidized gel-bound ferredoxin exhibited very low affinity for these enzymes but effectively bound both nitrate reductase and NADP reductase when reduced by dithionite.

[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 ...

We have identified and characterized novel types of ferredoxin and ferredoxin reductase from Arabidopsis. Among a number of potential ferredoxin reductase genes in the Arabidopsis genome, AtMFDR was identified to encode a homologue of mitochondrial ferredoxin reductase, and AtMFDX1 and AtMFDX2 were predicted to code for proteins similar to ...
