Protein
Leucoanthocyanidin dioxygenase
Organism
Arabidopsis thaliana
Function
Involved in anthocyanin and protoanthocyanidin biosynthesis by catalyzing the oxidation of leucoanthocyanidins into anthocyanidins. Possesses low flavonol synthase activity in vitro towards dihydrokaempferol and dihydroquercetin producing kaempferol and quercitin, respectively.
Similarity
Belongs to the iron/ascorbate-dependent oxidoreductase family.
