Pathway Edits

  • bAS beta-amyrin synthase overexpression initiating the pentacyclic triterpene scaffold in Stevia
  • CYP88D6 cytochrome P450 integration for C-11 and C-30 oxidation steps toward glycyrrhetic acid
  • CYP72A154 expression cassette for the C-30 carboxylation step in glycyrrhizin biosynthesis
  • UGT73P2 glucuronosyltransferase integration for first glucuronidation step toward glycyrrhizin
  • UGT91H4 expression for the second glucuronidation completing the glycyrrhizin disaccharide chain
  • HMGR upregulation for expanded triterpenoid precursor supply via enhanced MVA pathway flux
  • Competing flavonoid pathway suppression to redirect phenylpropanoid intermediates to triterpenoids
