Transport properties of Asp-51-->Glu and Asp-120-->Glu mutants of the melibiose carrier of Escherichia coli.

Biochimica et biophysica acta - 23 Mar 1994

Wilson D M, Wilson T H

Abstract excerpt

Asp-51-->Glu and Asp-120-->Glu mutants of the melibiose carrier of Escherichia coli were investigated for their cation/sugar cotransport properties. The carrier containing Glu-51 showed proton/melibiose cotransport but was extremely defective in Na+ or Li+ stimulation of sugar accumulation. On the other hand, the carrier containing Glu-120 had lost the ability to couple protons with melibiose uptake while...
