β‐Amyrin synthase from Conyza blinii expressed in Saccharomyces cerevisiae
Conyza blinii H.Lév. is a widely used medicinal herb in southwestern China. The main pharmacological components of C. blinii are a class of oleanane-type pentacyclic triterpene glycosides known as conyzasaponins, which are thought to be synthesized from β-amyrin. However, no genes involved in the conyzasaponin pathway have previously been identified. Here, we identify an oxidosqualene cyclase (...
متن کاملCloning and characterization of a β-amyrin synthase gene from the medicinal tree Aralia elata (Araliaceae).
Aralia elata is an important medicinal plant in China; it produces large amounts of oleanane type triterpene saponins. A full-length cDNA encoding β-amyrin synthase (designated as AeAS) was isolated from young leaves of A. elata by reverse transcription-PCR. The full-length cDNA of AeAS was found to have a 2292-bp open reading frame, encoding a protein with 763 amino acid residues. The ded...
متن کاملSaponin Biosynthesis in Saponaria vaccaria. cDNAs Encoding b-Amyrin Synthase and a Triterpene Carboxylic Acid Glucosyltransferase
Saponaria vaccaria (Caryophyllaceae), a soapwort, known in western Canada as cowcockle, contains bioactive oleanane-type saponins similar to those found in soapbark tree (Quillaja saponaria; Rosaceae). To improve our understanding of the biosynthesis of these saponins, a combined polymerase chain reaction and expressed sequence tag approach was taken to identify the genes involved. A cDNA encod...
متن کاملSensing bacteria, without bitterness?
In addition to their recognized roles in intra- and inter-species signaling, bacterial quorum-sensing molecules have been implicated in inter-kingdom signaling. A new study in Pseudomonas aeruginosa suggests that mammalian bitter taste receptors may recognize bacterial quorum sensing molecules, and widens the scope of such inter-kingdom communication. Intestinal cells also harbor these receptor...
