Application of metabolic engineering to the production of scopolamine.
Scopolamine is an alkaloid widely used in medicine for its anticholinergic activity. The aim of this review is to show that metabolic engineering techniques constitute a suitable tool to improve the production of tropane alkaloids, focusing in particular on scopolamine. We present an overview of results obtained by various research groups, including our own, who have studied the overexpression ...
متن کاملImprovement of tropane alkaloids production in hairy root cultures of Atropa belladonna by overexpressing pmt and h6h genes
Atropa belladonna L. is the commercial plant to produce tropane alkaloids including hyoscyamine and scopolamine, which are widely used as anticholinergic agents. In the present study, the genes encoding the key enzymes including putrescine N-methyltransferase (PMT) and hyoscyamine 6β-hydroxylase (H6H) were simultaneously overexpressed in transgenic hairy root cultures of A. belladonna. All of t...
متن کاملTropane and Granatane Alkaloid Biosynthesis: A Systematic Analysis.
The tropane and granatane alkaloids belong to the larger pyrroline and piperidine classes of plant alkaloids, respectively. Their core structures share common moieties and their scattered distribution among angiosperms suggest that their biosynthesis may share common ancestry in some orders, while they may be independently derived in others. Tropane and granatane alkaloid diversity arises from ...
متن کاملEnhancing Tropane Alkaloid Production Based on the Functional Identification of Tropine-Forming Reductase in Scopolia lurida, a Tibetan Medicinal Plant
Scopolia lurida, a native herbal plant species in Tibet, is one of the most effective producers of tropane alkaloids. However, the tropane alkaloid biosynthesis in this plant species of interest has yet to be studied at the molecular, biochemical, and biotechnological level. Here, we report on the isolation and characterization of a putative short chain dehydrogenase (SDR) gene. Sequence analys...
متن کاملAssessment of Morphological and Tropane Alkaloids Diversity among some Henbane (Hyoscyamus niger L.) Populations
Background: Black henbane with the scientific name of Hyoscyamus niger which has a wide geographic distribution, is considered as one the most important species for tropane alkaloids extraction. Objective: In this research, morphological and tropane alkaloids variations were assessed within different population of H. niger in their natural habitats. Methods: Totally, 56 individuals were colle...
