ENZYME entry: EC

Accepted Name
Tropinone reductase II.
Alternative Name(s)
Pseudotropine forming tropinone reductase.
Tropinone reductase.
Reaction catalysed
Pseudotropine + NADP(+) <=> tropinone + NADPH
  • Represents, along with EC, a branch point in tropane alkaloid metabolism.
  • Tropine (the product of EC is incorporated into hyoscyamine and scopolamine whereas pseudotropine (the product of EC is the first specific metabolite on the pathway to the calystegines.
  • Both enzymes are always found together in any given tropane-alkaloid- producing species, have a common substrate, tropinone, and are strictly stereospecific.
