Design of Hollow Nanoreactors for Size- and Shape-Selective Catalytic Semihydrogenation Driven by Molecular Recognition.

Mimicking the structures and functions of cells to create artificial organelles has spurred the development of efficient strategies for production of hollow nanoreactors with biomimetic catalytic functions. However, such structure are challenging to fabricate and are thus rarely reported. We report the design of hollow nanoreactors with hollow multishelled structure (HoMS) and spatially loaded metal nanoparticles.

[Heterologous biomimetic synthesis of active ingredients in traditional Chinese medicine:a new mode for protection and development of traditional Chinese medicine resources].

Heterologous biomimetic synthesis of the active ingredients of traditional Chinese medicine(TCM) is a new mode of resource acquisition and has shown great potential in the protection and development of TCM resources. According to synthetic biology and by constructing biomimetic microbial cells and imitating the synthesis of active ingredients in medicinal plants and animals, the key enzymes obtained from medicinal plants and animals are scientifically designed and systematically reconstructed and optimized to realize the heterologous synthesis of the active ingredients in microorganisms. This method ensures an efficient and green acquisition of target products, and also achieves large-scale industrial production, which is conducive to the production of scarce TCM resources.

[Prediction of superantigen active sites and clonal expression of staphylococcal enterotoxin-like W].

The docking and superantigen activity sites of staphylococcal enterotoxin-like W (SElW) and T cell receptor (TCR) were predicted, and its SElW was cloned, expressed and purified. AlphaFold was used to predict the 3D structure of SElW protein monomers, and the protein models were evaluated with the help of the SAVES online server from ERRAT, Ramachandran plot, and Verify_3D. The ZDOCK server simulates the docking conformation of SElW and TCR, and the amino acid sequences of SElW and other serotype enterotoxins were aligned.
