Mutagenesis of acidic residues in putative membrane-spanning segments of the melibiose permease of Escherichia coli. II. Effect on cationic selectivity and coupling properties.
Zani ML, Pourcher T, Leblanc G. Zani ML, et al. Among authors: leblanc g. J Biol Chem. 1993 Feb 15;268(5):3216-21. J Biol Chem. 1993. PMID: 8428998 Free article.
Individual substitution of Cys or Asn for Asp-31, Asp-51, Asp-55, or Asp-120, distributed in different membrane spanning segments of the NH2-terminal domain of melibiose (mel) permease partially or completely inactivates Na(+)-linked sugar transport and stimulation of sugar bindi …

Structural studies of the melibiose permease of Escherichia coli by fluorescence resonance energy transfer. II. Identification of the tryptophan residues acting as energy donors.
Cordat E, Mus-Veteau I, Leblanc G. Cordat E, et al. Among authors: leblanc g. J Biol Chem. 1998 Dec 11;273(50):33198-202. doi: 10.1074/jbc.273.50.33198. J Biol Chem. 1998. PMID: 9837888 Free article.
In the accompanying paper, we demonstrated the presence of a fluorescence resonance energy transfer (FRET) between the tryptophans of the melibiose permease (MelB) of Escherichia coli and a fluorescent sugar, 2'-(N-5-dimethylaminonaphthalene-1-sulfonyl)aminoethyl-1-thio-beta-D- g …
