ID   1.5.1.56
DE   3,17-didehydrostemmadenine reductase.
CA   17-dehydrostemmadenine + NADP(+) = 3,17-didehydrostemmadenine + NADPH.
CC   -!- The enzyme, characterized from the plant Catharanthus roseus
CC       (Madagascar periwinkle), participates in a biosynthetic pathway that
CC       leads to production of the bisindole alkaloid compounds vinblastine
CC       and vincristine, which are used as anticancer drugs.
CC   -!- Both the substrate and the product of the enzyme are unstable.
