Improvement 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 کاملEnhanced secretion of tropane alkaloids in Nicotiana tabacum hairy roots expressing heterologous hyoscyamine-6beta-hydroxylase.
Hyoscyamine-6beta-hydroxylase (H6H; EC 1.14.11.11) catalyses oxidative reactions in the biosynthetic pathway leading from hyoscyamine to the more pharmaceutically valuable tropane alkaloid scopolamine. The h6h gene encoding H6H from Hyoscyamus niger was introduced, under the control of the CaMV 35S promoter, into non-hyoscyamine-producing Nicotiana tabacum and hyoscyamine-producing Hyoscyamus m...
متن کاملA Comprehensive Overview on Valuable Tropane Alkaloids: Scopolamine, Atropine, and Hyoscyamine
Tropane alkaloids such as scopolamine (C17H21NO4), atropine (C17H23NO3) and hyoscyamine (C17H23NO3) are the most important plant secondary metabolites in the pharmaceutical industry due to anticholinergic activity, competition with muscarinic receptors and also treating different human diseases. Scopolamine, hyoscyamine and atropine are the most important tropane alkaloids used as anticoagulant...
متن کاملEffect of elicitation on antioxidant activity and production of tropane alkaloids in Hyoscyamus reticulatus hairy root cultures
Background and objectives: Hyoscyamus reticulatus contains two distinguished tropane alkaloids, hyoscyamineand scopolamine and both of the compounds possesspotential acute or chronic toxicity. In the present study, a simple and efficient transformation system was established for in vitro hairy roots induction in Hyoscyamus reticulatus. M...
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...
