The small molecule regacin binds a conserved pocket in RegA to inhibit the expression of bacterial virulence factors

Christopher M. Bollinger, Grace Lawhern, Kacey Marie Talbot, F. Jon Kull, Charles R. Midgett, George P. Munson

This paper identifies regacin as an inhibitor of RegA, a virulence regulator in Citrobacter rodentium, and defines its binding site through structural and mutagenesis studies.

Regulation and Characterization of the Cex system of enteric pathogens: a pathway for the lipidation and secretion of noncanoncial bacterial lipoproteins

Zachary P. Rivas, Kacey Marie Talbot, Griffin P. Carter, George P. Munson

This study characterizes the Cex system in enteric pathogens, showing that Rns regulates lipidation and secretion of noncanonical bacterial lipoproteins through a novel acyltransferase, CexD.

Characterization of the ligand binding pocket of the virulence regulator Rns, a Member of the AraC/XylS family of transcription factors

Jessica D. Tolbert, Kacey Marie Talbot, Christopher M. Bollinger, F. Jon Kull, George P. Munson, Charles R. Midgett

This study identifies key residues in the Rns binding pocket critical for fatty acid inhibition and structural rigidity, supporting the hypothesis that fatty acid binding inhibits AraC regulators in bacterial pathogens.

CexE Is A Virulence Factor of Citrobacter rodentium And Present In Enteric Pathogens Of Humans

Zachary Rivas, Ryan M. McCormack, Becky Adkins, George P. Munson

This study shows that CexE is a conditionally secreted virulence factor in Citrobacter rodentium and other enteric pathogens that enhances colonization in mice.

Perforin-2 Permeabilizes the Envelope of Phagocytosed Bacteria

Fangfang Bai, Ryan M. McCormack, Suzanne Hower, Gregory V. Plano, Mathias G. Lichtenheld, George P. Munson

This study shows Perforin-2 enables phagocytes to degrade bacterial antigens by breaching their envelope, enhancing bacterial killing.
