摘要: Provided is a microorganism that can display, on the cell surface, any molecules other than a molecule comprising amino acids, more specifically, a microorganism that displays biotin on a cell surface. The microorganism is capable of co-expressing a biotinylating enzyme and an acceptor peptide having a sequence recognized by the biotinylating enzyme, wherein the acceptor peptide is expressed on the cell surface, so that lysine of the acceptor peptide is biotinylated to display biotin on the cell surface. Also provided is a method for displaying an intended molecule, including not only a molecule comprising amino acids but also any molecules, on a cell surface of a microorganism.

摘要: The subject invention is hollow nanoparticles that comprise particle-forming first proteins (e.g. hepatitis B virus surface-antigen protein), containing a bio-recognizing molecule for recognizing a specific cell, wherein at least one of the first proteins interacts with a second protein (e.g. hepatitis B virus core-antigen protein) forming a capsid structure. With this structure, the present invention provides hollow nanoparticles, that allow transfer of a substance to a specific cell or tissue, and can be manufactured with stable productivity. The present invention further provides a drug made of the hollow nanoparticles.
