General description

Ferredoxin-NADP+ Reductase is a ferredoxin-soluble partner with a molar ratio to PSI of 0.9 and 3.

Application

Ferredoxin-NADP+ Reductase from Spinacia oleracea (spinach) has been used to test the effect of potential protein partners on the activity of the glyceraldehyde-3-phosphate dehydrogenase (GAPDH)−CP12 preparation. It has also been used in standard assay conditions for phycocyanobilin:ferredoxin oxidoreductase (PcyA) enzyme assay.
Ferredoxin-NADP+ Reductase was used in in vitro ferredoxin-dependent desaturation of fatty acids in cyanobacterial thylakoid membranes. It was also used to regulate glyceraldehyde-3-phosphate dehydrogenase.

Biochem/physiol Actions

Ferredoxin-NADP+ reductase catalyzes the reversible conversion of reduced ferredoxin to oxidized ferredoxin during photosynthesis. Ferredoxin-NADP(H) reductase constitutes a family of hydrophilic FAD-containing monomeric enzymes that deliver NADPH or low potential one-electron donors to redox-based metabolisms in plastids, mitochondria, and bacteria.

Unit Definition

One unit will reduce 1.0 millimole of cytochrome C per min at pH 7.5 at 25 °C in the presence of spinach ferredoxin and NADP.

To adapt to different light intensities, photosynthetic organisms manipulate the flow of electrons through several alternative pathways at the thylakoid membrane. The enzyme ferredoxin:NADP(+) reductase (FNR) has the potential to regulate this electron partitioning because it is integral to most

Plasmodium falciparum ferredoxin-NADP(+) reductase (FNR) is a FAD-containing enzyme that, in addition to be a promising target of novel antimalarial drugs, represents an excellent model of plant-type FNRs. The cofactor specificity of FNRs depends on differences in both k(cat) and
