Abstract

Carbohydrate utilization-related and multidrug transporter nucleic acids and polypeptides, and fragments and variants thereof, are disclosed in the current invention. In addition, carbohydrate utilization-related and multidrug transporter fusion proteins, antigenic peptides, and anti-carbohydrate utilization-related and anti-multidrug transporter antibodies are encompassed. The invention also provides vectors containing a nucleic acid of the invention and cells into which the vector has been introduced. Methods for producing the polypeptides and methods of use for the polypeptides of the invention are further disclosed.
