Enzyme Information
| 1.1.1.206 |
Tropinone reductase I.
based on mapping to UniProt P50162
Tropine + NADP(+) = tropinone + NADPH.
-!- Also oxidizes other tropan-3-alpha-ols, but not the corresponding beta-derivatives. -!- Represents, along with EC 1.1.1.236, 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.
