Pathway Edits

  • ScGCL1 gamma-glutamylcysteine ligase overexpression under PGK1 promoter for enhanced glutamate-to-gamma-glutamylcysteine ligation in yeast
  • ScGS glutathione synthase upregulation via synthetic TDH3 promoter for complete glutathione tripeptide synthesis from gamma-GC intermediate
  • ScGSR glutathione reductase overexpression to recycle GSSG to GSH, maintaining high reduced glutathione pool for mGluR1-modulating kokumi-umami activity
  • ScGLR1 glutaredoxin 1 activity upregulation for cytosolic redox buffering, preventing GSH oxidation and preserving gamma-glutamyl peptide pool
  • ScGPX2 glutathione peroxidase redirection variant for preferential GSSG reduction over peroxide scavenging, maximizing free GSH
