Arg-52 in the Melibiose Carrier of Escherichia coli Is Important for Cation-Coupled Sugar Transport and Participates in an Intrahelical Salt Bridge
Arg-52 of the Escherichia coli melibiose carrier was replaced by Ser (R52S), Gln (R52Q), or Val (R52V). While the level of carrier in the membrane for each mutant remained similar to that for the wild type, analysis of melibiose transport showed an uncoupling of proton cotransport and a drastic redu...
