Pseudomonas aeruginosa IscR-Regulated Ferredoxin NADP(+) Reductase Gene (fprB) Functions in Iron-Sulfur Cluster Biogenesis and Multiple Stress Response. [PDF]
PLoS One, 2015 P. aeruginosa (PAO1) has two putative genes encoding ferredoxin NADP(+) reductases, denoted fprA and fprB. Here, the regulation of fprB expression and the protein's physiological roles in [4Fe-4S] cluster biogenesis and stress protection are ...

Structural-functional characterization and physiological significance of ferredoxin-NADP reductase from Xanthomonas axonopodis pv. citri. [PDF]
PLoS One, 2011 Xanthomonas axonopodis pv. citri is a phytopathogen bacterium that causes severe citrus canker disease. Similar to other phytopathogens, after infection by this bacterium, plants trigger a defense mechanism that produces reactive oxygen species ...

Fluorescence Studies on Ferredoxin-NADP Reductase [PDF]
Zeitschrift für Naturforschung C, 1973 Abstract With highly purified preparations of ferredoxin-NADP reductase (EC 1.6.99.4; also EC 1.6.1.1) from spinach chloroplasts a strong flavin fluorescence was observed (excitation at 450 nm). At pH 7.0, the fluorescence was approximately 40% higher than that of free FAD.

Open questions in ferredoxin‐NADP+ reductase catalytic mechanism [PDF]
European Journal of Biochemistry, 2003 Ferredoxin (flavodoxin)‐NADP(H) reductases (FNR) are ubiquitous flavoenzymes that deliver NADPH or low potential one‐electron donors (ferredoxin, flavodoxin) to redox‐based metabolisms in plastids, mitochondria and bacteria. The plant‐type reductase is also the basic prototype for one of the major families of flavin‐containing electron transferases ...

Inhibition of pea ferredoxin–NADP(H) reductase by Zn‐ferrocyanide [PDF]
European Journal of Biochemistry, 2004 Ferredoxin–NADP(H) reductases (FNRs) represent a prototype of enzymes involved in numerous metabolic pathways. We found that pea FNR ferricyanide diaphorase activity was inhibited by Zn2+ (Ki 1.57 µm). Dichlorophenolindophenol diaphorase activity was also inhibited by Zn2+ (Ki 1.80 µm), but the addition of ferrocyanide was required, indicating that the

Effect of Ferredoxin on the Diaphorase Activity of Cyanobacterial Ferredoxin-NADP Reductase [PDF]
Plant Physiology, 1985 The interaction of ferredoxin-NADP reductase (FNR) and ferredoxin (Fd) results in an enhanced rate of reaction and a shift of the pH optimum for the FNR-mediated diaphorase reaction. Low concentrations of NaCl (

Biohybrid photosynthetic charge accumulation detected by flavin semiquinone formation in ferredoxin-NADP+ reductase. [PDF]
Chem Sci, 2022 Flavin chemistry is ubiquitous in biological systems with flavoproteins engaged in important redox reactions. In photosynthesis, flavin cofactors are used as electron donors/acceptors to facilitate charge transfer and accumulation for ultimate use in ...

Ferredoxin-NADP+ reductase from Pseudomonas putida functions as a ferric reductase. [PDF]
J Bacteriol, 2009 ABSTRACT Pseudomonas putida harbors two ferredoxin-NADP + reductases (Fprs) on its chromosome, and their functions remain largely unknown. Ferric reductase is structurally contained within the Fpr superfamily.

A cross-linked complex between ferredoxin and ferredoxin-NADP+ reductase.
Journal of Biological Chemistry, 1984 The water-soluble carbodiimide, N-ethyl-3-(3-dimethylaminopropyl)carbodiimide was found to effectively cross-link ferredoxin to ferredoxin-NADP+ reductase. The covalent complex has a stoichiometry of 1 mol of ferredoxin per mol of the reductase. The flavoprotein moiety of the cross-linked complex maintains most of its diaphorase activity and more ...
