ID 1.3.1.128 DE precondylocarpine acetate reductase. AN dihydroprecondylocarpine acetate synthase. CA dihydroprecondylocarpine acetate + NADP(+) = precondylocarpine acetate + CA NADPH + H(+). CC -!- The enzyme, characterized from the plant Catharanthus roseus CC (Madagascar periwinkle), participates in a pathway that leads to the CC production of a number of monoterpene alkaloids, as well as the CC bisindole alkaloids vinblastine and vincristine, which are used as CC anticancer drugs. CC -!- The enzyme forms the iminium ion form of dihydroprecondylocarpine CC acetate, which spontaneously rearranges and undergoes deacylation, CC producing dehydrosecodine.
