2R,3S,4S-cis-leucoanthocyanidin + 2-oxoglutarate + O2
cis- and trans-dihydroquercetins + succinate + CO2 + 2 H2O
-
catalyses the penultimate step in anthocyanin biosynthesis by oxidation of the 2R,3S,4S-cis-leucoanthocyanidins
both quercetin and dihydroquercetin are products with the distribution being dependent on the C-4 stereochemistry of the leucocyanidin substrates
