Abstract: The present invention relates to identification of inhibitors or antagonists of aminoarabinase glycosyltransferase (ArnT) and their use in compositions, methods of treatment or prevention of drug resistant gram negative infections, or inhibiting the growth of gram negative bacterial infections resistant to polymyxin-class antibiotics. In certain aspects, the inhibitors or antagonists can be administered in combination with one or more antibacterial agents.

Abstract: This invention provides methods for producing a membrane-bound protein in mammalian cells. This invention also provides nucleic acids for making novel fusion proteins (e.g., GPCR fusion proteins). This invention further provides related bacterial expression vectors; expression methods; fusion proteins; bacterial cells; GPCR vector screens; bacterial spheroplasts; methods for making anti-GPCR antibodies; and GPCR binding screens. This invention also provides a method for identifying a reagent in which a membrane protein is likely to crystallize. Finally, this invention provides methods for producing crystals of a protein which, in a cell, is a membrane-bound protein.
