CflP couples magnesium availability to CovS signaling in Group B Streptococcus

Oscar J. Vázquez-Ciros, Marília Martins Manta, Anna Riegner, Cameron W. Kenner, Yoann S. Le Breton, Kevin S. McIver, Nikolai Siemens, Konstantin V. Korotkov, Natalia Korotkova

This study identifies CflP as an accessory regulator of CovS in GBS, linking magnesium availability to virulence gene repression and immune cell cytotoxicity.

Enterococcus faecalis autolysin, EpaU, binds the enterococcal polysaccharide antigen via its teichoic acid-like repeats and modulates c-di-AMP signaling

Catherine T. Chaton, Nicholas R. Murner, Svetlana A. Zamakhaeva, Jeffrey S. Rush, Cameron W. Kenner, Alexander E. Yarawsky, Lei Huang, Parastoo Azadi, Andrew B. Herr, Natalia Korotkova, Konstantin V. Korotkov

This study identifies EpaU as an autolysin that binds the enterococcal polysaccharide antigen and modulates c-di-AMP signaling, affecting antibiotic resistance and cell turgor in Enterococcus faecalis.

The regulatory functions of ESX-1 substrates, EspE and EspF, are separable from secretion.

Rebecca J. Prest, Konstantin V. Korotkov, Patricia A. DiGiuseppe Champion

This study investigates the relationship between EspE and EspF secretion and their regulatory functions in mycobacteria, finding that their secretion is separable from their gene regulatory roles.
