Figure Lengend Snippet: Biosynthesis of monoterpene indole alkaloids. (A) Production of strictosidine from tryptamine and secologanin by the action of Catharanthus roseus strictosidine synthase (CrSTR). (B) Biosynthesis of stemmadenine acetate, an intermediate of the pathway for the production of the two anticancer compounds vinblastine and vincristine. The production of stemmadenine acetate involves 6 enzymes from strictosidine: CrSGD, CrGS, CrGO, CrReDOX1, CrReDOX2, and CrSAT. Akuammicine is a spontaneous degradation product of preakuammicine. (C) Biosynthesis of the antipsychotic molecule alstonine in Catharanthus roseus. The production of alstonine involves 3 enzymes from strictosidine: CrSGD, CrTHAS, CrAS.
