The invention relates to a recombinant Escherichia coli expressing a fusion protein of formamidase and phosphite dehydrogenase, a construction method and use thereof. The invention includes adopting engineered E. coli DH5α as a host, amplifying a cloned formamidase gene and a cloned phosphite dehydrogenase gene into a fusion gene, ligating the fusion gene to a multiple cloning site of a vector, transforming the obtained recombinant plasmid into the E. coli DH5α, extracting the plasmid and transforming into an expression strain, and performing induction culture to obtain a recombinant E. coli. The recombinant E. coli can express a fusion protein of formamidase and phosphite dehydrogenase.

An antibody that specifically binds to a glucocorticoid-induced tumor necrosis factor receptor (GITR), an antibody fragment and a polymer thereof, and a conjugate and a fusion comprising the antibody or the antibody fragment are provided in the present invention.

Disclosed are new nucleic acid base-editing systems comprising fusion proteins comprising a) an RNA-programmable nucleic acid recognition module or other suitable nucleic acid recognition module, b) a light inducible reactive oxygen generator. Further disclosed are methods and kits to modify or mutagenize a target DNA region in prokaryotic or eukaryotic cells or organisms.

In alternative embodiments, provided are compositions, including recombinant expression systems and vectors, products of manufacture and kits, and methods, for remotely-controlled and non-invasive manipulation of intracellular nucleic acid expression, genetic processes, function and activity in live cells such as T cells in vivo, for example, activating, adding functions or changing or adding specificities for immune cells, for monitoring physiologic processes, for the correction of pathological processes and for the control of therapeutic outcomes. In alternative embodiments, provided are blue-light-mediated light-inducible nuclear translocation and dimerization (LINTAD) systems for gene regulation to control cell activation based on the integration of light-sensitive LOV2-based nuclear localization, light-induced active transportation via the biLINuS motif, and CRY2-CIB1 dimerization that feature high spatiotemporal control to control or alter cell activities in vivo, for example, to limit CAR T cell activity to the tumor site for immunotherapy applications.
