Site-directed tryptophan fluorescence reveals two essential conformational changes in the Na(+)/H(+) antiporter NhaA
NhaA, a Na(+)/H(+) antiporter critical for pH and Na(+) homeostasis in Escherichia coli, as well as other enterobacteria and possibly Homo sapiens, was modified for fluorescence spectroscopy by constructing a functional Trp-less NhaA mutant. Purified Trp-less NhaA lacks the Trp fluorescence emission...
