Na +/H + Antiport Is Essential for Yersinia pestis Virulence

Creator:

Minato, Yusuke, Ghosh, Amit, Faulkner, Wyatt J., Lind, Erin J., Schesser Bartra, Sara, Plano, Gregory V., Jarrett, Clayton O., Hinnebusch, B. Joseph, Winogrodzki, Judith, Dibrov, Pavel, and Hase, Claudia C.

Abstract:

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...

Malonate Inhibits Virulence Gene Expression in Vibrio cholerae

Creator:

Minato, Yusuke, Fassio, Sara R., and Häse, Claudia C.

Abstract:

We previously found that inhibition of the TCA cycle, either through mutations or chemical inhibition, increased toxT transcription in Vibrio cholerae. In this study, we found that the addition of malonate, an inhibitor of succinate dehydrogenase (SDH), decreased toxT transcription in V. cholerae, an observation inconsistent with the previous pattern...

Sodium/Proton Antiporter Activity is Essential for Virulence of Yersinia pestis

Creator:

Faulkner, Wyatt J., Ghosh, Amit, Minato, Yusuke, Winogrodzki, Judith, Lind, Erin, Plano, Gregory V., Hinnebusch, Joseph B., Dibrov, Pavel, and Häse, Claudia C.

Abstract:

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....
