UniProtKB description:  Involved in the biosynthesis of cannabinoids-related terpenophenolic natural products, which have pharmacological activity (PubMed:18323613, PubMed:19454282, PubMed:19581347, PubMed:22802619). Polyketide synthase responsible for olivetol biosynthesis, from a C(12)-polyketide, probably 3,5,7-trioxododecanoyl-CoA (PubMed:19454282, Ref.3). Catalyzes the first step in the cannabinoids biosynthetic pathway. The preferred substrate is hexanoyl-CoA, but accepts also CoA esters with C4 to C8 aliphatic side chains (PubMed:19454282). When using malonyl-CoA and hexanoyl-CoA as substrates, produces undetermined compounds distinct form olivetol or olivetolic acid (PubMed:19581347) that could be hexanoyl triacetic acid lactone (HTAL) (PubMed:18323613) and pentyl diacetic acid lactone (PDAL) (PubMed:22802619). Produces olivetolic acid when acting in concert with olivetolic acid cyclase (OAC).
