The new beta-D-glucosidase in terpenoid-isoquinoline alkaloid biosynthesis in Psychotria ipecacuanha. [PDF]
J Biol Chem, 2008 Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. Deglucosylation of one of the condensed products N-deacetylisoipecoside (1 alpha(S)-epimer) is considered to be a part of the ...

Is a metabolic enzyme complex involved in the efficient and accurate control of Ipecac alkaloid biosynthesis in Psychotria ipecacuanha? [PDF]
Plant Signal Behav, 2010 Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. The condensation products are deglucosylated, and the resulting aglycon is further processed to protoemetine, which is condensed with
