ENZYME entry: EC 1.1.1.236
Accepted Name |
Tropinone reductase II.
|
Alternative Name(s) |
Pseudotropine forming tropinone reductase. |
TR-II. |
Tropinone reductase. |
Reaction catalysed |
Pseudotropine + NADP(+) <=> tropinone + NADPH |
Comment(s) |
- Represents, along with EC 1.1.1.206, a branch point in tropane
alkaloid metabolism.
- Tropine (the product of EC 1.1.1.206) is incorporated into
hyoscyamine and scopolamine whereas pseudotropine (the product of
EC 1.1.1.236) 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.
