Pathway Edits

  • GmPrB proteinase B vacuolar serine protease overexpression under seed-specific promoter for systematic storage protein hydrolysis releasing free glutamate and aspartate
  • GmLAP leucine aminopeptidase upregulation for exoprotease cleavage of N-terminal amino acids from protein hydrolysate fragments, amplifying free amino acid yield
  • GmCPY carboxypeptidase Y homolog introduction from Saccharomyces for C-terminal amino acid liberation complementing LAP N-terminal hydrolysis
  • GmVPE vacuolar processing enzyme isoform 1 overexpression for asparaginyl endopeptidase-driven protein fragmentation at internal Asn/Asp sites
  • GmSPI serine protease inhibitor partial knockdown (40%) to relieve endogenous inhibition of introduced protease activities
  • GmLTP lipid transfer protein 1 suppression to reduce subcellular membrane barrier limiting protease-substrate contact in protein bodies
  • GmPSA proteasome subunit alpha overexpression for enhanced ubiquitin-dependent protein turnover feeding free amino acid pool
  • GmNPR non-specific protease R introduction from Bacillus subtilis for broad-spectrum protein hydrolysis under neutral pH conditions

Key Interventions

Protease cascade engineering for systematic storage protein hydrolysis yielding free glutamate, aspartate, and nucleotide co-agonists in soybean seedExo- and endoprotease co-engineering targeting complete protein fragment hydrolysis for maximum free amino acid liberationAmino acid permease upregulation ensuring liberated free amino acids reach cytosolic compartment for mGluR1-accessible pool formation
