Ancient Cannabinoid Enzymes

Wageningen University & Research scientists reconstructed long-extinct cannabis enzymes to reveal how the plant first began producing cannabinoids such as THC, CBD, and CBC. Using ancestral sequence reconstruction, the team revived these ancient biocatalysts in the lab, featuring enzyme variants that existed in early cannabis relatives millions of years ago. Their work experimentally traced how modern cannabinoid pathways emerged from more generalized chemical machinery.

The researchers showed that early enzymes were biochemical multitaskers, able to generate several cannabinoids at once before evolution split them into today’s specialized forms. These resurrected enzymes were expressed in microorganisms like yeast, where they proved more robust and easier to handle than their modern counterparts. One reconstructed enzyme displayed particularly strong specificity for CBC, a compound associated with anti-inflammatory and pain-relief properties.

For consumers and brands, this research signals a shift toward precisely engineered cannabinoid production and next-generation medical cannabis varieties. More stable, flexible ancestral enzymes can streamline biotech manufacturing and enable tailored cannabinoid profiles without relying solely on plant cultivation. This approach sets the groundwork for pharmaceutical-grade formulations and novel cannabis strains that emphasize lesser-known molecules like CBC, aligning with broader trends in precision wellness and evidence-based botanical therapeutics.
