Pathway Edits

  • GCL-high (high-activity GCL variant) overexpression via strong constitutive promoter
  • Gly-I-RNAi (glyoxalase I) silencing to prevent competitive GSH completion and retain γ-Glu-Cys
  • gamma-ECS (γ-glutamylcysteine synthetase) activity optimization for dipeptide accumulation
  • ACS1 (1-aminocyclopropane-1-carboxylate synthase 1) carbon flux rerouting to cysteine precursors
  • Cysteine transporter upregulation for cytosolic cysteine pool expansion
  • GGT4 retrograde catabolism attenuation to stabilize accumulated γ-Glu-Cys pool

Key Interventions

GCL-high amplification for γ-Glu-Cys dipeptide as direct CaSR kokumi ligand without GSH completionGly-I-RNAi silencing to prevent competing reactions and maximize γ-Glu-Cys pool for CaSR engagementgamma-ECS intermediate channeling to favor dipeptide accumulation over tripeptide completionAgrobacterium-mediated T-DNA delivery optimized for Allium sativum genome accessibilityTier-I construct validated with 3 precision edits for 1.4× fold-change
