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

Key Interventions

Glutathione CaSR + mGluR1 dual-activation engineering via elevated gamma-glutamyl peptide pool for kokumi-umami bridging activityGCL/GS pathway amplification for GSH accumulation targeting gamma-glutamyl peptide-mediated umami roundness and bodyGSH pool oxidation prevention via GSR/GLR1 redox engineering for sustained kokumi-umami activity through fermentation
