Pathway Edits
- GGT1 (γ-glutamyl transpeptidase 1) Val-Gly specificity maturation via active-site remodeling
- GGT4 isoform expression cassette for parallel γ-glutamyl transfer pathway activation
- ALT2 (alanine aminotransferase 2) competitive glutamate sink removal for GGT substrate enrichment
- Vacuolar V-type protease expression for dipeptide scaffold liberation from storage protein
- γ-Glu-Val-Gly tripeptide vacuolar export permease upregulation for cytosolic accumulation
- GDH1 (glutamate dehydrogenase 1) overexpression for GGT donor substrate pool expansion
- GAD1 partial silencing to redirect glutamate from GABA shunt toward GGT reaction
