Accepted name: codeine 3-O-demethylase
Reaction: codeine + 2-oxoglutarate + O2 = morphine + formaldehyde + succinate + CO2
Other name(s): codeine O-demethylase; CODM
Systematic name: codeine,2-oxoglutarate:oxygen oxidoreductase (3-O-demethylating)
Comments: Requires Fe2+. Catalyses a step in morphine biosynthesis. The enzyme also catalyses the 3-O-demethylation of thebaine to oripavine, with lower efficiency.
