This disclosure provides an E. coli strain, which lacks thioredoxin reductase activity encoded by trxB and thioredoxin 1 activity encoded by trxA, and glutathione reductase activity encoded by gor. Said E. coli strain expresses a mutated AhpC protein having glutathione reductase activity and a cytosolic prokaryotic disulfide isomerase. The E. coli strain has an oxidative cytosol and can be used to efficiently produce proteins having disulfide bonds.

The disclosed subject matter provides for genetically modified cells, e.g., fungal cells, that autonomously generates and/or secretes one or more therapeutic molecules, e.g., therapeutic peptides, therapeutic proteins or small therapeutic molecules, in situ. In certain embodiments, the present disclosure provides genetically-engineered fungal cells that generate and secrete tetracycline and analogues thereof.

This invention relates to a plant E3 ubiquitin ligase (termed DA2) which acts synergistically with DA1 to control seed and organ size. Methods of increasing plant yield are provided that comprise reducing the expression or activity of DA2 in a plant that is deficient in DA1 expression or activity. Plants with increased yield and methods of producing such plants are also provided.

The invention relates to compositions including polynucleotides encoding polypeptides which have been chemically modified by replacing the uridines with 1-methyl-pseudouridine to improve one or more of the stability and/or clearance in tissues, receptor uptake and/or kinetics, cellular access by the compositions, engagement with translational machinery, mRNA half-life, translation efficiency, immune evasion, protein production capacity, secretion efficiency, accessibility to circulation, protein half-life and/or modulation of a cell's status, function, and/or activity.

The present disclosure relates to engineered ketoreductase polypeptides for the preparation of hydroxyl substituted carbamate compounds, and polynucleotides, vectors, host cells, and methods of making and using the ketoreductase polypeptides.

The invention relates to the field of medical diagnosis, particularly to methods and antibodies useful for the identification of colibactin producing bacteria (pks+ bacteria). Herein are disclosed peptides and antibodies that allow for the detection and isolation of pks+ bacteria, as well as uses and methods of use of said peptides and antibodies.

The present invention provides a method of synthesizing celosianin II, a method of synthesizing a betaxanthin, an amyloid-β polymerization inhibitor or a therapeutic or preventive agent for Alzheimer's, an amyloid peptide aggregation inhibitor, and an HIV-1 protease activity inhibitor. A gene having a celosianin II synthesis ability has been isolated from quinoa, and a method of synthesizing celosianin II of the present invention has been constructed. Besides, it has been recognized that celosianin II or the like serves as an active ingredient of each of an amyloid-β polymerization inhibitor or a therapeutic or preventive agent for Alzheimer's, an amyloid peptide aggregation inhibitor, and an HIV-1 protease activity inhibitor.

Genetically programmed microorganisms, such as bacteria or virus, pharmaceutical compositions thereof, and methods of modulating and treating cancers are disclosed.

Provided herein are compositions and methods for altering sensitivity of target cells to killing by γδ T cells.

The present invention relates to a method for diagnosis of bile duct cancer, using methionyl-tRNA synthetase (MRS) in bile duct cells of a latent patient.
