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.

Affinity labeling of spinach ferredoxin-NADP+ oxidoreductase with periodate-oxidized NADP+
Archives of Biochemistry and Biophysics, 1984Periodate-oxidized NADP+ (dialdehyde-NADP+) inactivated soluble ferredoxin-NADP+ oxidoreductase and combined covalently to the enzyme. This inactivation was first order with respect to dialdehyde-NADP+ and followed saturation kinetics, indicating that the enzyme initially forms a reversible complex with the inactivator.

Trends in Microbiology, 1998
Catabolite repression is a central multigene regulatory network that enables bacteria to select and utilize the optimal carbon and energy sources available in a given environment. Cyclic AMP and catabolite gene activator protein (CAP) play central roles in mediating catabolite repression in enteric bacteria but are absent from Gram-positive bacteria ...

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.

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.

A lysyl residue at the NADP binding site of ferredoxin-NADP reductase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1976Dansyl chloride, at low molar ratio, inactivates ferredoxin-NADP reductase (NADPH:ferredoxin oxidoreductase, EC 1.6.7.1). The complete protection afforded either by NADP or NADPH suggests a direct involvement of the active site. Experiments with [Me-14C] dansyl chloride showed that about 1.5 residues per flavin were dansylated: by differential ...

Enzymatic Synthesis of Caged NADP Cofactors: Aqueous NADP Photorelease and Optical Properties
The Journal of Organic Chemistry, 2000The synthesis of caged NADP analogues 18, 19, and 20 has been accomplished by utilizing the transglycosidase activity of solubilized NAD glycohydrolase (porcine brain) to incorporate caged nicotinamides 2, 3, and 4 into NADP. The synthesis of several nicotinamides modified at the carboxamide with o-nitrobenzyl photolabile groups is demonstrated as well

Abstract The plastidic ferredoxin-NADP + reductase from the xanthophycean alga Bumilleriopsis forms a stoichiometric 1:1 complex with ferredoxin and NADP + which is demonstrated by difference spectra of both complexes. Butanedione modification of the flavoprotein results in loss of its enzymatic activities (transhydrogenase and diaphorase ...

Analogues of NADP+ as inhibitors and coenzymes for NADP+ malic enzyme from maize leaves
Photosynthesis Research, 1991Structural analogues of the NADP(+) were studied as potential coenzymes and inhibitors for NADP(+) dependent malic enzyme from Zea mays L. leaves. Results showed that 1, N(6)-etheno-nicotinamide adenine dinucleotide phosphate (∈ NADP(+)), 3-acetylpyridine-adenine dinucleotide phosphate (APADP(+)), nicotinamide-hypoxanthine dinucleotide phosphate (NHDP(+

Structure of ferredoxin-NADP+ oxidoreductase and the location of the NADP binding site
Journal of Molecular Biology, 1981Abstract Ferredoxin-NADP + oxidoreductase is the enzyme responsible for catalyzing the production of NADPH during photosynthesis. The structure of “ferredoxin reductase” has been elucidated at 3.7 A resolution by the method of multiple isomorphous replacement with anomalous scattering.
