Abstract
Described herein are prenyltransferases including non-natural variants thereof having at least one amino acid substitution as compared to its corresponding natural or unmodified prenyltransferases and that are capable of at least two-fold greater rate of formation of cannabinoids such as cannabigerolic acid, cannabigerovarinic acid, cannabigerorcinic acid, and cannabigerol, as compared to a wild type control. Prenyltransferase variants also demonstrated regioselectivity to desired cannabinoid isomers such as CDBA (3-GOLA), 3-GDVA, 3-GOSA, and CBG (2-GOL). The prenyltransferase variants can be used to form prenylated aromatic compounds, and can be expressed in an engineered microbe having a pathway to such compounds, which include 3-GOLA, 3-GDVA, 3-GOSA, and CBG. 3-GOLA can be used for the preparation of cannabigerol (CBG), which can be used in therapeutic compositions.
