  • PRODUCTION OF GPP AND CBGA IN A METHYLOTROPHIC YEAST STRAIN
    Publication number: 20230043569
    Abstract: This invention is an improved method of robust and scalable production of precursors of active cannabinoids, including geranyl pyrophosphate (GPP) and/or cannabigerolic acid (CBGA), in a methylotrophic yeast host cell. The improved methods incorporate a polypeptide encoding an Erg20 variant (F98W/N128W) into a methylotrophic yeast host cell, for example Pichia pastoris (Komagataella phaffii), that biases the natural production of FPP and GPP towards GPP, a precursor to the intermediate CBGA, crucial to the synthesis of active cannabinoids.
