ENZYME entry: EC 1.14.20.6

Accepted Name
flavonol synthase
Alternative Name(s)
flavonoid 2-oxoglutarate-dependent dioxygenase
FLS
Reaction catalysed
2-oxoglutarate + a (2R,3R)-dihydroflavonol + O2 = a flavonol + CO2 + H2O + succinate
Comment(s)
  • In addition to the desaturation of (2R,3R)-dihydroflavonols to flavonols, the enzyme from the satsuma Citrus unshiu 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.
  • Formerly EC 1.14.11.23.
