General annotation (Comments)

Function

Catalyzes the formation of flavonols from dihydroflavonols. It can act on dihydrokaempferol to produce kaempferol, on dihydroquercetin to produce quercitin and on dihydromyricetin to produce myricetin By similarity.

Catalytic activity

A dihydroflavonol + 2-oxoglutarate + O2 = a flavonol + succinate + CO2 + H2O.

A flavanone + 2-oxoglutarate + O2 = a dihydroflavonol + succinate + CO2.

Cofactor

Binds 1 iron ion per subunit By similarity.

Binds 1 ascorbate molecule per subunit By similarity.

Pathway

Secondary metabolite biosynthesis; flavonoid biosynthesis.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the iron/ascorbate-dependent oxidoreductase family.
