Role of protons in sugar binding to LacY

WT lactose permease of Escherichia coli (LacY) reconstituted into proteoliposomes loaded with a pH-sensitive fluorophore exhibits robust uphill H(+) translocation coupled with downhill lactose transport. However, galactoside binding by mutants defective in lactose-induced H(+) translocation is not a...
