Recombinant microorganisms, plants, and plant cells are disclosed that have been engineered to express novel recombinant genes encoding steviol biosynthetic enzymes and UDP-glycosyltransferases (UGTs). Such microorganisms, plants, or plant cells can produce steviol or steviol glycosides, e.g., rubusoside or Rebaudioside A, which can be used as natural sweeteners in food products and dietary supplements.

The invention relates to recombinant microorganisms and methods for producing manoyl oxide.

The invention relates to recombinant microorganisms and methods for producing steviol glycosides and steviol glycoside precursors.

Recombinant microorganisms are disclosed that produce steviol glycosides and have altered expression of one or more endogenous transporter or transcription factor genes or that overexpress one or more heterologous transporters, leading to increased excretions of steviol glucosides of interest.

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 UGT76G1. 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 rebaudioside M.

The present disclosure features compositions and methods for producing one or more isoprenoid compounds, such as gamma-ambryl acetate (GAA), in a host cell, such as a yeast cell, that is genetically modified to express the enzymes of an isoprenoid biosynthetic pathway, such as a pathway for making GAA. Using the compositions and methods of the present invention, the host cell may be genetically modified to express one or more enzymes of an isoprenoid biosynthetic pathway, such as an enzyme capable of converting manooloxy to GAA. The host cell may be cultured in a medium, for example, in the presence of an agent that regulates expression of the one or more enzymes. The host cell may be incubated for a time sufficient to allow for production of an isoprenoid compound, such as GAA. The isoprenoid compound may then be separated from the host cell or from the medium.

The invention relates to recombinant microorganisms and methods for producing macrocyclic diterpene or oxidized macrocyclic diterpene.

The present invention concerns a method of producing and enantiomerically pure alpha-ionone. Further, the invention concerns a nucleic acid that comprises a sequence that encodes a lycopene-epsilon-cyclase (EC), a lycopene-epsilon-cyclase (EC), plasmids, which encode components of the alpha-ionone biosynthesis and a microorganism that contains heterologous nucleotide sequences which encode the enzymes geranylgeranyl-diphosphate-synthase, isopentenyl-diphosphate-isomerase (IPI), phytoene desaturase-dehydrogenase (crtI), phytoene synthase (crtB), lycopene-epsilon-cyclase (EC) and carotenoid-cleavage-dioxygenase (CCD1). Further, the invention concerns a method of producing highly pure epsilon-carotene.

Provided herein are recombinant cells (e.g., recombinant bacteria or plant, insect, mammalian, and yeast cells) containing a nucleic acid encoding a CYP97A protein or a nucleic acid encoding a CYP97B protein; a nucleic acid encoding a CYP97C protein; a nucleic acid encoding a geranylgeranyl pyrophosphate synthase protein; a nucleic acid encoding a phytoene synthase protein; a nucleic acid encoding a phytoene desaturase protein; a nucleic acid encoding a lycopene -cyclase protein; and a nucleic acid encoding a lycopene -cyclase protein. Also provided are methods of producing lutein that include culturing these recombinant cells (e.g., recombinant bacteria and yeast cells), and methods of generating these recombinant cells (e.g., recombinant bacteria and yeast cells). Also provided is lutein produced by these methods, and pharmaceutical compositions, food supplements, food products, and cosmetic compositions that contain lutein produced by these methods.

The invention relates to recombinant microorganisms and methods for producing steviol glycosides and steviol glycoside precursors.
