Prenylation of olivetolate by a hemp transferase yields cannabigerolic acid, the precursor of tetrahydrocannabinol

Abstract

A new enzyme, geranylpyrophosphate:olivetolate geranyltransferase (GOT), the first enzyme in the biosynthesis of cannabinoids could be detected in extracts of young leaves of Cannabis sativa. The enzyme accepts geranylpyrophosphate (GPP) and to a lesser degree also nerylpyrophosphate (NPP) as a cosubstrate. It is, however, specific for olivetolic acid; its decarboxylation product olivetol is inactive as a prenyl acceptor.
