Protein
3,5,7-trioxododecanoyl-CoA synthase
Function
Polyketide synthase responsible for olivetol biosynthesis. 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. 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).
Similarity
Belongs to the thiolase-like superfamily. Chalcone/stilbene synthases family.
