Pathway Edits

  • GmGGT1 gamma-glutamyltransferase 1 overexpression under seed-specific 7S globulin promoter for gamma-glutamyl dipeptide generation from storage protein glutamate
  • GmGGT4 isoform 4 upregulation for cytosolic gamma-glutamyltranspeptidase activity expansion in cotyledon cells
  • GmALT alanine aminotransferase overexpression for enhanced alanine supply as gamma-glutamyl-alanine dipeptide second residue
  • GmAlaAT alanine:pyruvate aminotransferase activity boost for pyruvate-to-alanine flux supporting GGT1-mediated dipeptide synthesis
  • GmLAP leucine aminopeptidase partial suppression to slow gamma-glutamyl dipeptide hydrolysis preserving intact peptide pool
  • GmVPE vacuolar processing enzyme activity modulation for controlled seed protein hydrolysis releasing glutamyl peptide fragments
  • GmPSI protease inhibitor I overexpression to suppress serine proteases that degrade glutamyl dipeptides in mature seed
  • GmGS1a glutamine synthetase cytosolic isoform upregulation for enhanced free glutamate pool feeding GGT-mediated peptide assembly

Key Interventions

Gamma-glutamyl dipeptide accumulation via GGT1/GGT4 upregulation for mGluR1-activating peptide umami effect in soy productsGlutamyl-alanine and glutamyl-valine dipeptide co-accumulation targeting umami roundness and body beyond free glutamateProtease suppression maintaining intact gamma-glutamyl peptide pool through seed maturation and food processing
