We previously reported that inhibition of the Na⁺ translocating NADH:ubiquinone oxidoreductase (NQR), either by chemical inhibition or mutation, increased toxT transcription in Vibrio cholerae. In this study, we revealed that the nqr mutant strain showed similar phenotypes as the Escherichia coli NADH dehydrogenase I (nuo) mutant strain (e.g. growth defect...

The Na⁺ translocating NADH:quinone oxidoreductase (Na⁺-NQR) is a unique respiratory enzyme catalyzing the electron
transfer from NADH to quinone coupled with the translocation of sodium ions across the membrane. Typically, Vibrio spp.,
including Vibrio cholerae, have this enzyme but lack the proton-pumping NADH:ubiquinone oxidoreductase (Complex I).
Thus, Na⁺-NQR should significantly...

We found that a strains of Yersinia pestis (KIM5) which lacked the nhaA gene was fully attenuated in a plague model. This gene produces a protein of the sodium-proton antiporter family which expel sodium ions from the bacterial cytoplasm in exchange for hydrogen ions, or protons, from the surrounding environment....

Na⁺/H⁺ antiporters are ubiquitous membrane proteins that play a central role in the ion homeostasis of cells. In this study, we examined the possible role of Na⁺/H⁺ antiport in Yersinia pestis virulence and found that Y. pestis strains lacking the major Na⁺/H⁺ antiporters, NhaA and NhaB, are completely attenuated in...
