ENZYME entry: EC 1.14.11.31

Accepted Name
Thebaine 6-O-demethylase.
Reaction catalysed
Thebaine + 2-oxoglutarate + O(2) <=> neopinone + formaldehyde + succinate + CO(2)
Cofactor(s)
Fe(2+).
Comment(s)
  • Requires Fe(2+).
  • Catalyzes a step in morphine biosynthesis.
  • The product neopinione spontaneously rearranges to the more stable codeinone.
  • The enzyme also catalyzes the 6-O-demethylation of oripavine to morphinone, with lower efficiency.
