Geranyl Pyrophosphate Synthase
Geranyl pyrophosphate synthase (GPPS) is a key enzyme in the cannabis terpenoid biosynthesis pathway, catalyzing the condensation of isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) to form geranyl pyrophosphate (GPP). GPP serves as the C10 precursor for monoterpenoid production—compounds like myrcene, limonene, and pinene commonly detected in cannabis chemotypes. Breeders and biochemists track GPPS activity as a foundational step in understanding monoterpene-dominant phenotypes. Variations in GPPS expression and enzyme efficiency influence the overall terpenoid profile and aromatic character of cultivars.

Breeders working with monoterpene-forward strains often monitor GPPS activity indirectly through offspring terpenoid ratios and headspace analysis. Enhanced GPPS expression is associated with lineages selected for pronounced myrcene or pinene-dominant signatures, though direct genetic selection for this enzyme remains limited in public breeding programs.
