Molecular heterogeneity of ferredoxin-NADP+ reductase from spinach leaves
Biochemical and Biophysical Research Communications, 1983Highly purified ferredoxin-NADP+ reductase from spinach leaves showed at least eight different protein bands in the electrofocused gel. All of them were catalytically active and were adsorbed on a ferredoxin-Sepharose 4B affinity column. The N-terminal amino acid sequence of the main component species was analyzed by the automatic Edman degradation ...

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 ...

Photogeneration of NADPH by oligothiophenes coupled with ferredoxin-NADP reductase
Journal of Biotechnology, 1998The photogeneration of nicotinamide adenine dinucleotide hydrophosphate (NADPH) and its associated reaction were studied in a novel photo-energy conversion system. The system was composed of the oligothiophene, dimethyl-4,4′-bipyridinium (MV2+), EDTA, and combined with ferredoxin-NADP reductase (FDR, E.C.1.18.1.2).

On the Enzymology of Ferredoxin-NADP Reductase
1972Properties and location of this Enzyme (EC 1.6.99.4 or/and 1.6.1.1) within the photosynthetic electron transport chain were described in detail (AVRON & JAGENDORF 1956, KEISTER et al 1960, 1962, SHIN & ARNON 1965, SHIN 1968, FORTI & ZANETTI 1967). The enzyme reduces NADP with ferredoxin as the electron donor (reductase activity).

Spirulina Ferredoxin-NADP+ Reductase. The Complete Amino Acid Sequence1
The Journal of Biochemistry, 1984The amino acid sequence of ferredoxin-NADP+ oxidoreductase [EC 1.18.1.2, FNR] from Spirulina sp., a blue-green alga, was determined. Spirulina ferredoxin-NADP+ oxidoreductase was composed of 294 amino acid residues and the molecular weight of the holoenzyme was 34,135.

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.

Molecular heterogeneity of ferredoxin-NADP+ reductase from spinach leaves
Biochimica et Biophysica Acta (BBA) - Enzymology, 1977Ferredoxin-NADP+ reductase (NADPH: ferredoxin oxidoreductase, EC 1.6.7.1) from spinach leaves has been purified according to a new procedure. The enzyme shows the presence of five molecular forms as identified by isoelectric focusing, namely a, b, c, d and e with pI values of 6.0, 5.5, 5.2, 5.0 and 4.8, respectively.

Spirulina Ferredoxin-NADP+ Reductase. Further Characterization with an Improved Preparation1
The Journal of Biochemistry, 1983The preparation procedure for Spirulina ferredoxin-NADP+ reductase (ferredoxin: NADP+ oxidoreductase, EC 1.18.1.2, FNR) was improved by adding protease inhibitors, phenylmethylsulfonylfluoride (PMSF) and EDTA, through the whole process of preparation and by introducing an affinity chromatography step on Blue Sepharose CL-6B.

How is ferredoxin-NADP reductase involved in the NADP photoreduction of chloroplasts?
Photosynthesis Research, 2004NADP photoreduction of chloroplasts was discovered in 1951, and subsequent research was conducted to elucidate the enzymatic mechanisms involved in this reaction. In 1963, ferredoxin-NADP reductase (FNR; EC 1.18.1.2, ferredoxin-NADP oxidoreductase) was isolated and purified to a crystalline form.
