ENZYME entry: EC 1.1.1.334

Accepted Name
Methylecgonone reductase.
Reaction catalysed
Ecgonine methyl ester + NADP(+) <=> ecgonone methyl ester + NADPH
Comment(s)
  • The enzyme from the plant Erythroxylum coca catalyzes the penultimate step in the biosynthesis of cocaine.
  • In vivo the reaction proceeds in the opposite direction.
  • With NADH instead of NADPH the reaction rate is reduced to 14%.
  • The enzyme also reduces tropinone, nortropinone and 6-hydroxytropinone but with lower reaction rates.
