Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With 2-oxoglutarate as one donor, and incorporation of one atom of oxygen into each donor
Requires Fe2+. Catalyses a step in morphine biosynthesis. The product neopinione spontaneously rearranges to the more stable codeinone. The enzyme also catalyses the 6-O-demethylation of oripavine to morphinone, with lower efficiency.
