Pathway Edits

  • C-S lyase (cysteine-sulfoxide lyase) upregulation for propyl-cysteine sulfoxide cleavage and DPS precursor liberation
  • Propylcysteine sulfoxide (PCSO) biosynthesis pathway amplification via propyl-substituted cysteine S-oxidase
  • FMO3 (flavin-dependent monooxygenase 3) upregulation for S-oxidation of S-propyl-L-cysteine to propyl sulfoxide form
  • GGT-mediated gamma-glutamyl-S-propylcysteine processing pathway enhancement
  • Alliinase-family enzyme isoform with propyl-substrate specificity introduction for PCSO hydrolysis

Key Interventions

C-S lyase/PCSO pathway amplification for dipropyl disulfide (DPS) TRPA1 agonist accumulation in Allium sativum platformFMO3-driven propyl-cysteine S-oxidation maximizes PCSO precursor pool for C-S lyase substrate availabilityDPS TRPA1 activation confirmed by calcium-flux assay; dipropyl disulfide engages TRPA1 electrophilic binding site with characteristic onion-sulfur pungency profilePEG-mediated transient expression protocol validated for rapid phenotypic pathway screening

Use Case

Tier II DPS-enriched Allium ingredient for cooked-onion and mild garlic flavor profiles in processed foods, TRPA1-selective sulfurous pungency in soups, stews, and savory condiments requiring a less pungent but warm, penetrating sulfur character. Suitable for applications where allicin's sharp raw-garlic volatility is undesirable but TRPA1-mediated warmth and sulfurous depth are targeted flavor attributes.
