Transamination Pathways

Transamination pathways describe biochemical processes where amino groups are transferred between compounds, influencing volatile production in cannabis. These metabolic routes are foundational to how plants synthesize nitrogen-containing aroma compounds, including various sulfur-containing and nitrogenous volatiles. Breeders studying terpene and aromatic compound inheritance often examine transamination activity as a metabolic marker affecting final bouquet profiles. The conversion of amino acids to their corresponding α-keto acids—catalyzed by aminotransferases—generates precursors for secondary metabolites. Understanding these pathways helps explain phenotypic variation in aroma expression across genetically similar cultivars and is central to breeding for specific aromatic signatures.

Breeders working with line stabilization monitor transamination efficiency as an indirect measure of volatile production capacity and metabolic vigor. Selecting parent plants with consistent aminotransferase activity can improve aroma trait heritability and reduce expression variability in offspring.
