Expression vector for fusion gene and method for producing immobilized enzyme

摘要

The present invention enables immobilization of a useful protein, for example, a glycosyltransferase, onto the surface of a yeast cell without deteriorating its enzyme activity. The present invention provides a fusion gene expression vector which is characterized by containing a fusion gene that comprises a gene encoding a useful protein bound downstream of a gene encoding a yeast cell wall protein; a transformant yeast, which is transformed with the fusion gene expression vector; and an immobilized enzyme, which is characterized in that the expressed useful protein is immobilized on a yeast cell wall.
