Application

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.

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. 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.

General description

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

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.
