    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.

    Abstract: A non-naturally occurring eukaryotic or prokaryotic organism includes one or more gene disruptions occurring in genes encoding enzymes imparting increased fumarate, malate or acrylate production in the organism when the gene disruption reduces an activity of the enzyme. The one or more gene disruptions confers increased production of acrylate onto the organism. Organisms that produce acrylate have an acrylate pathway that at least one exogenous nucleic acid encoding an acrylate pathway enzyme expressed in a sufficient amount to produce acrylate, the acrylate pathway comprising a decarboxylase. Methods of producing fumarate, malate or acrylate include culturing these organisms.

    Abstract: The invention provides a non-naturally occurring microbial biocatalyst including a microbial organism having a 4-hydroxybutanoic acid (4-HB) biosynthetic pathway having at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase, or α-ketoglutarate decarboxylase, wherein the exogenous nucleic acid is expressed in sufficient amounts to produce monomeric 4-hydroxybutanoic acid (4-HB). Also provided is a non-naturally occurring microbial biocatalyst including a microbial organism having 4-hydroxybutanoic acid (4-HB) and 1,4-butanediol (BDO) biosynthetic pathways, the pathways include at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase, 4-hydroxybutyrate:CoA transferase, 4-butyrate kinase, phosphotransbutyrylase, α-ketoglutarate decarboxylase, aldehyde dehydrogenase, alcohol dehydrogenase or an aldehyde/alcohol dehydrogenase, wherein the exogenous nucleic acid is expressed in sufficient amounts to produce 1,4-butanediol (BDO). Additionally provided are methods for the production of 4-HB and BDO.
