Cysteine-scanning mutants, E32C to G62C, of the metal-tetracycline/H+ antiporter were constructed in order to precisely determine the membrane topology around putative transmembrane segment II. None(More)
Cysteine-scanning mutants as to putative transmembrane segments 4 and 5 and the flanking regions of Tn10-encoded metal-tetracycline/H(+) antiporter (TetA(B)) were constructed. All mutants were(More)
Putative transmembrane helices (TM) 1 and 11 in the metal-tetracycline/H(+) antiporter are predicted to be close to each other on the basis of disulfide cross-linking experiments of the(More)
