Described herein are devices and methods for increasing the production of steviol glycosides, which have industrial and economic value. The steviol glycosides produced by the devices and methods disclosed herein do not require the ultra purification that is common in conventional or commercial methods and do not have a bitter aftertaste, making them better suited as flavor-enhancing additives to food, pharmaceutical, and nutritional supplement products.

The present invention is in the technical field of synthetic biology and metabolic engineering. More particularly, the present invention is in the technical field of fermentation of metabolically engineered host cells. The present invention describes a method of making sialylated oligosaccharide by fermentation with a genetically modified cell, as well as to the genetically modified cell used in the method. The genetically modified cell comprises at least one nucleic acid sequence coding for an enzyme involved in sialylated oligosaccharide synthesis and at least one nucleic acid expressing a membrane protein.

An L-methionine-producing microorganism into which a metZ gene is introduced and a method of producing L-methionine using the same.

The invention relates to the field of cell culture technology. It concerns the knockdown, using RNA interference, or gene knockout, of activating transcription factor 6 beta (ATF6B), or the combination of ceramide synthase 2 (CERS2) and TBC1 domain family member 20 (TBC1D20) proteins, which play central roles in the cellular secretion pathway. This downregulation leads to improved secretion of biopharmaceutically relevant products produced in mammalian cells. The invention specifically relates to mammalian cells having enhanced secretion of a recombinant therapeutic protein compared to a control cell, a method of producing said mammalian cell, a method for the production of a recombinant secreted therapeutic protein and the use of said mammalian cell for increasing the yield of a recombinant secreted therapeutic protein.

Compositions and methods comprising polynucleotides and polypeptides having EPSP (5-enolpyruvylshikimate-3-phosphate) synthase (EPSPS) activity are provided. In specific embodiments, the sequence has an improved property, such as, but not limited to, improved catalytic capacity in the presence of the inhibitor, glyphosate. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the EPSPS sequences. Various methods of employing the EPSPS sequences are provided. Such methods include methods for producing a glyphosate tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein.

The present disclosure provides modified looped proteins comprising at least one looped region, wherein the at least one looped region comprises a cell penetrating peptide (CPP). In some embodiments, the present disclosure provides polynucleotides encoding the modified looped proteins and methods for their production.

The invention provides compositions and methods for suppressing autoimmune components of neurodegenerative diseases and thereby providing therapeutic effects to patients suffering from such diseases, Compositions and methods include immunosuppressive moieties such as regulatory T cells (Tregs) and proteins expressed by Tregs coupled to a chimeric antigen receptor or protein that specifically binds one or more glial cell markers. Therapeutically effective doses of said compounds for treating neurodegenerative diseases including progressive supranuclear palsy (PSP), Parkinson's disease (PD), Alzheimer's, Huntington's disease, amyotrophic lateral sclerosis (ALS), chronic traumatic encephalopathy (CTE), multiple sclerosis, and prion diseases are disclosed.

Provided herein, in some aspects, are compositions and methods for treating Barth syndrome (BTHS) using human tafazzin gene therapy or enzyme replacement therapy. The present disclosure, in some aspects, provides compositions and methods (e.g., gene therapy or enzyme replacement therapy) for treating Barth syndrome (BTHS). It was demonstrated herein that certain human Tafazzin (hTAZ) isoforms and the full length protein, as well as nucleic acids encoding them, are effective in treating BTHS.

The present invention relates generally to the identification novel UDP-glucosyltransferases enzymes having specific activity towards cannabinoid compounds. The present invention further relates generally to the use of novel UGT enzymes having specific activity towards cannabinoid compounds to generate water-soluble cannabinoid glycoside compounds.

Compositions comprising an engineered or non-naturally occurring polypeptides comprising two or more domains selected from Sulfide quinone oxidoreductase, Thiosulfate Sulfurtransferase and persulfide dioxygenase, and a phosphate binding motif are provided along with methods of detoxifying bacterial endotoxins and H.sub.2S with such compositions.
