Described herein are olivetolic acid cyclases (OAC) including non-natural variants capable of forming a 2,4-dihydroxy-6-alkylbenzoic acid from a 3,5,7-trioxoacyl-CoA or a 3,5,7-trioxocarboxylate substrate. In some examples, the non-natural OAC is capable of forming a 2,4-dihydroxy-6-alkylbenzoic acid from a 3,5,7-trioxoacyl-CoA or a 3,5,7-trioxocarboxylate substrate at a greater rate. In some examples, the non-natural OAC has a higher affinity for a 3,5,7-trioxoacyl-CoA or a 3,5,7-trioxocarboxylate substrate, as compared to the wild type OAC. The non-natural OAC can be used with olivetol synthase (OLS) to form the 2,4-dihydroxy-6-alkylbenzoic acid from malonyl-CoA and acyl-CoA through a 3,5,7-trioxoacyl-CoAintermediate. The non-natural OAC (and OLS) can be expressed in an engineered cell having a pathway to form cannabinoids, which include CBGA, its analogs and derivatives. CBGA can be used for the preparation of cannabigerol (CBG), which can be used in therapeutic compositions.
