BRITE hierarchy
Sysname
codeine,2-oxoglutarate:oxygen oxidoreductase (3-O-demethylating)
Reaction(IUBMB)
codeine + 2-oxoglutarate + O2 = morphine + formaldehyde + succinate + CO2 [RN:R09402]
Reaction(KEGG)
R09402;
(other) R05127
Show
Substrate
codeine [CPD:C06174];
2-oxoglutarate [CPD:C00026];
O2 [CPD:C00007]
Product
morphine [CPD:C01516];
formaldehyde [CPD:C00067];
succinate [CPD:C00042];
CO2 [CPD:C00011]
Comment
Requires Fe2+. Catalyses a step in morphine biosynthesis. The enzyme also catalyses the 3-O-demethylation of thebaine to oripavine, with lower efficiency.
