Reaction: thebaine + 2-oxoglutarate + O2 = neopinone + formaldehyde + succinate + CO2
Other name(s): T6ODM
Systematic name: thebaine,2-oxoglutarate:oxygen oxidoreductase (6-O-demethylating)
Comments: 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.
