Abstract: The compositions and methods of the disclosure can be used to produce a cannabinoid in a host cell, such as a yeast cell. For example, the disclosure features host cells (e.g., yeast cells) modified to express one or more enzymes of a cannabinoid biosynthetic pathway, such as an acyl activating enzyme (AAE), a tetraketide synthase (TKS), a cannabigerolic acid synthase (CBGaS), and/or an olivetolic acid cyclase (OAC).

Abstract: Provided herein are genetically modified host cells, compositions, and methods for improved production of steviol glycosides. The host cells are genetically modified to contain a heterologous nucleic acid that expresses novel and optimized variants of Ro.KAH. The host cell further contains one or more heterologous nucleotide sequence encoding further enzymes of a pathway capable of producing one or more steviol glycosides in the host cell. The host cells, compositions, and methods described herein provide an efficient route for the heterologous production of steviol glycosides including rebaudioside A, rebaudioside D, and rebaudioside M.

Abstract: The present disclosure provides recombinant bacteria with elevated production of ethanol and/or n-butanol from ethylene. Methods for the production of the recombinant bacteria, as well as for use thereof for production of ethanol and/or n-butanol are also provided.
