The present application relates to a method of preparing urate oxidase (Uox) including a non-nature amino acid (NNAA) and Uox prepared thereby. The present application showed that the method of preparing Uox including an NNAA may be effectively used to prolong the half-life of a protein which is difficult to be linked to a carrier.

In addition, the Uox produced by the method may be effectively used for various biopharmaceuticals since its efficacy is maintained and drug persistency increases due to site-specific conjugation of a carrier, a risk of an immune response is reduced, and it is easily separated due to formation of uniform conjugate.

A genetically engineered microorganism for the production of a cannabinoid is described. The genetically engineered microorganism comprises at least one nucleic acid molecule encoding at least one cannabinoid biosynthetic pathway enzyme. The disclosure also relates to methods for producing a cannabinoid using a genetically engineered microorganism.

Synthetic cannabinoid compounds for treatment of pain and anxiety by administering to an individual in need thereof a pharmaceutical composition including a compound having the structure:

##STR00001##

or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable vehicle therefor.

A sensor implanted in tissues and including a sensing layer is fabricated by mixing the signal transduction enzyme with non-reactive components including buffer salts and fillers, and spin coating the enzyme onto a substrate. The signal transduction enzyme is crosslinked by introducing the coated substrate in a vacuum chamber. In the chamber, a crosslinker evaporates and is deposited onto the enzyme, therefore crosslinking the enzyme.

Described herein are anti-microbial and UV-protective biological devices and extracts produced therefrom. The biological devices include microbial cells transformed with a DNA construct containing genes for producing proteins such as, for example, zinc-related protein/oxidase, silicatein, silaffin, and alcohol dehydrogenase. In some instances, the biological devices also include a gene for lipase. Methods for producing and using the devices are also described herein. Finally, compositions and methods for using the devices and extracts to kill microbial species or prevent microbial growth and to reduce or prevent UV-induced damage or exposure to materials, items, plants, and human and animal subjects are described herein. Also disclosed are biological devices producing polyactive carbohydrates and carbo sugars, as well as compositions and articles incorporating both extracts from these devices and the anti-microbial and UV-protective extracts.

Disclosed herein are methods for N-demethylating an N-methylated compound using an enzymatic reaction, rather than, e.g. a chemical modification. Also provided herein are enzymes for performing the reaction.

Disclosed are genetically engineered organisms, such as yeast and bacteria, that have the ability to metabolize atypical phosphorus or sulfur sources. Fermentation methods using the genetically engineered organisms are also described. The fermentation methods are robust processes for the industrial bioproduction of a variety of compounds, including commodities, fine chemicals, an pharmaceuticals.

A mutant cytochrome protein originated from a cytochrome protein having three heme-binding domains, which mutant cytochrome protein lacks the first heme-binding domain and the second heme-binding domain as counted from the N-terminus, is provided. The mutant cytochrome protein may lack a region(s) containing the first and second heme-binding domains.

The invention discloses a construction method of genetic engineering fungi of filamentous fungi. Through the genetic engineering method, the filamentous fungi overexpress the positive regulation genes of ethanol synthesis, and/or down regulate the negative regulation genes of endogenous ethanol synthesis to obtain genetic engineering strains. Or overexpression of acetaldehyde dehydrogenase and ethanol dehydrogenase containing mitochondrial localization signal sequence, or overexpression of pyruvate decarboxylase and ethanol dehydrogenase containing mitochondrial localization signal sequence, or overexpression of acetaldehyde dehydrogenase, ethanol dehydrogenase and pyruvate decarboxylase containing mitochondrial localization signal sequence in filamentous fungal cells. Compared with the original strain, the ethanol synthesis ability of the obtained genetically engineered strains are improved.
