DE   Leucocyanidin oxygenase.
AN   Anthocyanidin synthase.
AN   Leucoanthocyanidin dioxygenase.
CA   Leucocyanidin + 2-oxoglutarate + O(2) = cis- and trans-dihydroquercetins
CA   + succinate + CO(2) + H(2)O.
CF   Iron; L-ascorbic acid.
CC   -!- Involved in the pathway by which many flowering plants make
CC       anthocyanin (glycosylated anthocyandin) flower pigments.
CC   -!- The intermediates are transformed into cis- and trans-
CC       dihydroquercetin, which the enzyme can also oxidize to quercetin.
CC   -!- Acidification of the products gives anthocyanidin, which, however,
CC       may not be a natural precursor of the anthocyanins.
