Identification
Name:Ferredoxin--NADP reductase
Synonyms:
  • FNR
  • DA1
  • Flavodoxin reductase
  • FLDR
  • FLXR
  • Methyl viologen resistance protein A
Gene Name:fpr
Enzyme Class:
Biological Properties
General Function:Involved in oxidoreductase activity
Specific Function:Transports electrons between flavodoxin or ferredoxin and NADPH. Involved in the reductive activation of cobalamin- independent methionine synthase, pyruvate formate lyase and anaerobic ribonucleotide reductase. Also protects against superoxide radicals due to methyl viologen in the presence of oxygen
