The present disclosure provides genetically modified host cells that produce a cannabinoid, a cannabinoid derivative, a cannabinoid precursor, or a cannabinoid precursor derivative. The present disclosure provides methods of synthesizing a cannabinoid, a cannabinoid derivative, a cannabinoid precursor, or a cannabinoid precursor derivative.

The present invention relates to a recombinant microorganism which is capable of simultaneously fermenting at least two sugars in a lignocellulosic saccharified liquid, and also capable of generating diol.

Disclosed herein include methods, compositions, and kits suitable for use in detecting the activation level of a signal transducer. In some embodiments, there are provided synthetic protein circuits wherein recruitment of synthetic protein circuit components to an association location upon activation of a signal transducer generates an active effector protein. The effector protein can be configured to carry out a variety of functions when in an active state, such as, for example, inducing cell death. Methods of treating a disease or disorder characterized by aberrant signaling are provided in some embodiments.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a Serine Protease Inhibitor Kazal-type (SPINK) polypeptide (e.g., a SPINK5 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of Netherton Syndrome); and articles of manufacture or kits thereof.

Disclosed are gene engineering bacteria for producing L-arginine and a construction method and an application of the gene engineering bacteria. According to the method, genes encoding a carbamoyl phosphate synthetase and a gene encoding an L-arginine biosynthesis pathway enzyme are integrated into Escherichia coli; the present invention has analyzed and reconstructed the arginine synthetic pathway and the metabolic flow related to arginine in the entire amino acid metabolic network in E. coli and finally obtained a genetically engineered bacterial strain which has a clear genetic background, carries no plasmids, undergoes no mutagenesis and is capable of stably and efficiently producing L-arginine.
