The molecular weight of this enzyme has not been analyzed. The enzymatic assay states a solubility of 1 mg/ ml in water.
Immediately prior to pipetting into cuvette, prepare a solution at 1 mg / mL in cold purified water. Place on ice.
This solution is stable for a maximum of thirty minutes.

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 was used in in vitro ferredoxin-dependent desaturation of fatty acids in cyanobacterial thylakoid membranes.[1] It was also used to regulate glyceraldehyde-3-phosphate dehydrogenase.[2]
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.
Biochem/physiol Actions
Ferredoxin-NADP+ reductase catalyzes the reversible conversion of reduced ferredoxin to oxidized ferredoxin during photosynthesis.[3] 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.[4]

Other Notes
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.

Hi, how can I prepare a stock solution with the 1 U vial? It's not very clear for me in the specification sheet. I need a 1 uM final concentration of reductase for my assay, how do I prepare a stock solution of it?

Hi there, could you please provide the specific methodology to extract this lyophilized powder from the vial? I didn't know how to extract this ferredoxin-NADP+ reductase from the vial
1 answer-
The vials contain less than 1mg solid so reconstituting the whole vial is recommended.
