Pathway Edits

GGT1 (γ-glutamyl transpeptidase 1) catalytic activity optimization via active-site engineering
GGT4-high (high-expression GGT4 isoform) overexpression cassette for parallel transfer pathway
GGT-VAC (vacuolar GGT isoform) expression for substrate mobilization from vacuolar GSH pool
AA-perm (amino acid permease) upregulation for acceptor substrate import and GGT reaction rate
Glutamate donor pool expansion via GS feedback-loop attenuation
Transpeptidase specificity maturation for preferred acceptor amino acid bias toward CaSR ligands

Key Interventions

GGT1/GGT4-high dual-isoform overexpression for high-flux γ-glutamyl transpeptidation producing diverse CaSR ligandsGGT-VAC vacuolar isoform expression for mobilization of vacuolar GSH pool into free γ-glutamyl peptide productsAA-perm acceptor substrate import upregulation for maximum GGT reaction rate and product diversityProtoplast PEG-fusion delivery optimized for Allium sativum genome accessibilityTier-I construct validated with 4 precision edits for 1.51× fold-change
