IUBMB Comments
In addition to the desaturation of (2R,3R)-dihydroflavonols to flavonols, the enzyme from Citrus unshiu (satsuma mandarin) also has a non-specific activity that trans-hydroxylates the flavanones (2S)-naringenin and the unnatural (2R)-naringenin at C-3 to kaempferol and (2R,3R)-dihydrokaempferol, respectively . Requires Fe2+.
