ID   1.1.1.236
DE   tropinone reductase II.
AN   pseudotropine forming tropinone reductase.
AN   TR-II.
AN   tropinone reductase.
CA   NADP(+) + pseudotropine = H(+) + NADPH + tropinone.
CC   -!- Represents, along with EC 1.1.1.206, a branch point in tropane
CC       alkaloid metabolism.
CC   -!- Tropine (the product of EC 1.1.1.206) is incorporated into
CC       hyoscyamine and scopolamine whereas pseudotropine (the product of
CC       EC 1.1.1.236) is the first specific metabolite on the pathway to the
CC       calystegines.
CC   -!- Both enzymes are always found together in any given tropane-alkaloid-
CC       producing species, have a common substrate, tropinone, and are
CC       strictly stereospecific.
