Substrates: in the absence of olivetolic acid cyclase (OAC), a nonenzymatic C2 -> C7 decarboxylative aldol condensation of the tetraketide intermediate occurs forming olivetol. The apparent plasticity of the enzyme with only minor alterations in amino acid sequences demonstrates the subtle nature of the mechanistic discrimination. This involves interplay between multiple residues, an inherently flexible active site designed to accommodate a growing scaffold and easily convertible cyclization mechanism(s) with minimal intervention

application of transPACT, a phylogenomic algorithm to automate global classification of trans-AT polyketide synthase modules across bacteria. Polyketide synthases are grouped into PKSs that are conserved in a variety of different producers and putatively responsible for the biosynthesis of identical or closely related polyketides. The second PKS category comprises enzymes that harbor a conserved module block corresponding to a shared polyketide substructure. Thirdly common motifs present only in orphan PKSs may identify biosynthetic diversity in genome mining studies

synthesis

a synthetic pathway for the production of olivetolic acid in Escherichia coli is developed. Through combining OLA synthase and OLA cyclase expression with the required modules of a beta-oxidation reversal for hexanoyl-CoAgeneration, we demonstrate the in vivo synthesis of olivetolic acid from a single carbon source. The integration of additional auxiliary enzymes to increase hexanoyl-CoA and malonyl-CoA, along with evaluation of varying fermentation conditions enabled the synthesis of 80 mg/l olivetolic acid. Olivetolic acid has various pharmacological activities
synthesis
engineering of Cannabis sativa olivetolic acid cyclase and tetraketide synthase with F24I and L190G substitutions, respectively, in the biosynthesis of DELTA9-THC serves as a platform for the generation of resorcylic acids up to 6-undecylresorcylic acid
