| additional information | usage of 4-coumaroyl-CoA and malonyl-CoA as substrates, resulting product is naringenin, not resveratrol. The enzyme might show a broad specificity of substrate including aliphatic substrates such as isovaleryl-CoA, isobutyryl-CoA, and n-hexanoyl-CoA | Cannabis sativa | ? | - |

| physiological function | polyketide synthases play an important role in the biosynthesis of secondary metabolites such as resveratrol, a candidate for cancer chemoprevention and naringenin, the precursor for flavonoids. Olivetolic acid is also be expected to be synthesized by a PKS | Cannabis sativa |
