General Information | Comment | Organism |
---|---|---|
evolution | the enzyme belongs to the plant DFR superfamily, phylogenetic analysis | Saussurea medusa |
metabolism | the DFR gene is a key gene late in the flavonoid biosynthesis pathway, overview. The enzyme posesses flavanone 4-reductase activity and also is a key enzyme in the biosynthesis of anthocyanidins, proanthocyanidins, and other flavonoids | Saussurea medusa |
physiological function | the enzyme is of importance in plant development | Saussurea medusa |
