Expression of cholera toxin B subunit in Saccharomyces cerevisiae

English Abstract

Cholera toxin, secreted by Vibrio cholerae, consists of A and B subunits. Cholera toxin B subunit (CTB) is used in many scientific research. It has already been expressed in several bacterial and plant systems. In order to express CTB protein in Saccharomyces cerevisiae, the expression plasmid pCTB83 was constructed by inserting ctxB gene in pYES2 shuttle vector. The new construct was transferred into S. cerevisiae cells and the ctxB gene was induced with 2% galactose. SDS-PAGE analysis showed the presence of CTB in yeast lysate and immunoblotting analysis of yeast total soluble protein indicated that the yeast-derived CTB protein was antigenically indistinguishable from bacterial CTB protein. Quantitative ELISA showed that the maximum amount of CTB protein expressed in yeast was approximately 1.8% of total soluble protein. CTB is a subunit vaccine candidate against cholera. Since the whole recombinant yeast has been introduced as a new vaccine formulation, expression of ctxB in S. cerevisiae may offer an effective and inexpensive strategy to protect people against cholera in high-risk areas.
