Abstract

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.
