-4-azi-pentane and chloroacetone were condensed with β-D- thiosugars to yield β-D-thioglycosides which either already had a photolabile diazirino group or they had an oxo group, which could be converted into such. All photolabile β-thio-glycosides are excellent competitive inhibitors for their corresponding glycoside hydrolases (β-D-galactosidase and β-D-glucosidase). Photolysis of the glycosides in

The present invention relates to an adeno-associated virus with site-directed mutagenesis and site-specific modification, and a preparation method and uses thereof. Specifically, the present invention uses genetic code expansion techniques to incorporate non-natural amino acid into an adeno-associated virus capsid protein VP1 or fragment thereof, thereby obtaining an adeno-associated virus with site-directed mutagenesis using the non-natural amino acid. The adeno-associated virus with site-directed mutagenesis is equivalent to a wild-type virus in terms of production, transduction and mobility, can couple with other functional molecules, such as targeting molecules, and can carry a functional gene in a normal manner, which indicates that the adeno-associated virus with site-directed mutagenesis can be used as a tool adeno-associated virus, and applied in various aspects associated with adeno-associated virus such as finding adeno-associated virus binding proteins or using as target genetic therapy vector.

The disclosure provides for mass spectrometry (MS)-cleavable heterobifunctional photoactivated cross-linkers. The MS-cleavable heterobifunctional photoactivated cross-linkers can be used in mass spectrometry to facilitate structural analysis of intra-protein interactions in proteins and inter-protein interactions in protein complexes.
