    An enzyme switch, termed “Switchbody”, is developed by fusing an antibody with a fragment of a split enzyme for the precise regulation of enzyme activity in response to an antigen. A luciferase‐based Switchbody is engineered by fusing the NanoLuc luciferase fragment HiBiT to the N‐terminus of an antibody. The enzyme activity of the Switchbody increases upon the addition of an antigen in a dose‐dependent manner in the presence of the complementary fragment LgBiT and its substrate furimazine, demonstrating the potential of the luciferase‐based Switchbody as a biosensor. As its working principle, ELISA shows that the interaction between HiBiT and LgBiT is facilitated by antigen binding. Moreover, X‐ray crystallography and NMR reveal the heterogeneous trapped state of the HiBiT region and an increasing motility of HiBiT region upon antigen binding, respectively. MD simulations and luminescence measurements show that antigen disrupted the trapping of HiBiT in the antibody, enabling its release. By applying this “Trap and Release” principle to Protein M, an antibody‐binding protein, label‐free IgG antibodies are successfully converted into bioluminescent Switchbodies. This adaptable Switchbody platform has the potential to expand switching technology beyond luciferase to various other enzymes in the future.

    Microbial secretory protein expression is widely used for biopharmaceutical protein production. However, establishing genetically modified industrial strains that secrete large amounts of a protein of interest is time-consuming. In this study, a simple and versatile high-throughput screening method for protein-secreting bacterial strains is developed. Different genotype variants induced by mutagens are encapsulated in microemulsions and cultured to secrete proteins inside the emulsions. The secreted protein of interest is detected as a fluorescence signal by the fluorescent immunosensor quenchbody (Q-body), and a cell sorter is used to select emulsions containing improved protein-secreting strains based on the fluorescence intensity. The concept of the screening method is demonstrated by culturing Corynebacterium glutamicum in emulsions and detecting the secreted proteins. Finally, productive strains of fibroblast growth factor 9 (FGF9) are screened, and the FGF9 secretion increased threefold compared to that of parent strain. This screening method can be applied to a wide range of proteins by fusing a small detection tag. This is a highly simple process that requires only the addition of a Q-body to the medium and does not require the addition of any substrates or chemical treatments. Furthermore, this method shortens the development period of industrial strains for biopharmaceutical protein production.
