Abstract excerpt

The D-glucose/D-galactose-binding protein (GGBP) of Escherichia coli serves as an initial component for both chemotaxis toward D-galactose and D-glucose and high-affinity active transport of the two sugars. GGBP is a monomer with a molecular weight of about 32 kDa that binds glucose with micromolar affinity. The sugar-binding site is located in the cleft between the two lobes of the bilobate protein. In this...
