A recombinant cell of Saccharomyces cerevisiae that includes in its genome nucleic acids encoding cannabinoid biosynthetic pathway genes. A cannabinoid is produced by the recombinant cell in the presence of a cannabinoid precursor substrate and at least one of the cannabinoid biosynthetic pathway genes is from an organism other than Cannabis sativa, wherein the at least one of the cannabinoid biosynthetic pathway genes encodes a prenyltransferase. In an embodiment, the prenyltransferase is NphB from Streptomyces sp. having the amino acid sequence of any one of SEQ ID NOs: 8-11. Also disclosed is a method for producing a cannabinoid with the recombinant cell and the cannabinoid precursor substrate.

The present invention relates to a recombinant organism or microorganism having a decreased pool of crotonic acid compared to the organism or microorganism from which it is derived due to at least one of: (i) an increased conversion of crotonyl-CoA into butyryl-CoA; and/or an increased conversion of butyryl-CoA into butyric acid; (ii) an increased conversion of crotonyl-CoA into 3-hydroxybutyryl-CoA; and/or an increased conversion of 3-hydroxybutyryl-CoA into 3-hydroxybutyric acid; (iii) an increased conversion of crotonic acid into crotonyl-CoA; (iv) an increased conversion of crotonyl-[acyl-carrier protein] into butyryl [acyl-carrier-protein]; (v) a decreased conversion of crotonyl-CoA into crotonic acid; and/or (vi) a decreased conversion of crotonyl-[acyl-carrier protein] into crotonic acid. Moreover, the present invention relates to the use of such a recombinant organism or microorganism for the production of alkenes with the enzyme ferulic acid decarboxylase. Further, the present invention relates to a method for the production of isobutene or butadiene by culturing such a recombinant organism or microorganism in a suitable culture medium under suitable conditions.
