Acylated Steryl Glycoside Synthesis in Seedlings of Nicotiana tabacum L.
In tobacco seedlings (Nicotiana tabacum L.), glucose from supplied uridine diphosphate-[U-(14)C]glucose was first incorporated into steryl glycosides and later into acylated steryl glycosides. However, when [(14)C]cholesterol was used as substrate, the acylated steryl glycosides became labeled earlier than the steryl glycosides. With [(14)C]cholesteryl glucoside as substrate, most of the radioa...
متن کاملInhibition of steryl glycoside biosynthesis by acyl coenzyme a and by digitonin.
ATP, GTP, CoA, Mg(2+), and Mn(2+) did not inhibit biosynthesis of steryl glycoside and acylated steryl glycoside when added singly to enzyme preparations from spinach leaves. The combination of ATP (but not GTP), CoA, and Mg(2+) or Mn(2+) caused marked inhibition, especially of steryl glycoside biosynthesis, when reaction mixture concentrations of the additions were 0.2 millimolar. Inhibition w...
متن کاملMolecular Cloning and Biochemical Characterization of a Recombinant Sterol 3-O-Glucosyltransferase from Gymnema sylvestre R.Br. Catalyzing Biosynthesis of Steryl Glucosides
Gymnema sylvestre R.Br., a pharmacologically important herb vernacularly called Gur-Mar (sugar eliminator), is widely known for its antidiabetic action. This property of the herb has been attributed to the presence of bioactive triterpene glycosides. Although some information regarding pharmacology and phytochemical profiles of the plant are available, no attempts have been made so far to decip...
متن کاملThe role of Arabidopsis ABCG9 and ABCG31 ATP binding cassette transporters in pollen fitness and the deposition of steryl glycosides on the pollen coat.
The pollen coat protects pollen grains from harmful environmental stresses such as drought and cold. Many compounds in the pollen coat are synthesized in the tapetum. However, the pathway by which they are transferred to the pollen surface remains obscure. We found that two Arabidopsis thaliana ATP binding cassette transporters, ABCG9 and ABCG31, were highly expressed in the tapetum and are inv...
متن کاملGenomic and coexpression analyses predict multiple genes involved in triterpene saponin biosynthesis in Medicago truncatula.
Saponins, an important group of bioactive plant natural products, are glycosides of triterpenoid or steroidal aglycones (sapogenins). Saponins possess many biological activities, including conferring potential health benefits for humans. However, most of the steps specific for the biosynthesis of triterpene saponins remain uncharacterized at the molecular level. Here, we use comprehensive gene ...
