Elucidation of structure-function relationship of THCA and CBDA synthase from Cannabis sativa L.

Journal of Biotechnology

“Cannabinoids are secondary natural products from the plant Cannabis sativa L.

Therapeutic indications of cannabinoids currently comprise a significant area of medicinal research.

We have expressed the Δ9-tetrahydrocannabinolic acid synthase (THCAS) and cannabidiolic acid synthase (CBDAS) recombinantly in Komagataella phaffii and could detect eight different products with a cannabinoid scaffold after conversion of the precursor cannabigerolic acid (CBGA).

Besides five products remaining to be identified, both enzymes were forming three major cannabinoids of C. sativa – Δ9-tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA) and cannabichromenic acid (CBCA).

These studies lay the groundwork for further research as well as biotechnological cannabinoid production.”
