The evolution of a Na+-sensitive Vibrio cholerae mutant unmasks the moonlighting aminopeptidase PepA as a regulator of nhaB Na+/H+ antiporter gene expression

Sebastian Herdan, Katharina Kohm, Robert Warneke…·Julia Steuber

This study identifies PepA as a regulator of nhaB gene expression in Vibrio cholerae, revealing its role in Na+ homeostasis through suppressor mutations in a nhaA nqr mutant.

Plasmid copy number affects the DNA methylation-driven expression dynamics of the CfrBI restriction-modification system and impacts phage restriction

Johannes Gibhardt, Trung Duc Hoang, Konstantin Severinov…·Natalia Evgenevna Morozova

This study shows that plasmid copy number affects the expression dynamics and phage resistance of the CfrBI R-M system, with medium-copy plasmids providing the highest resistance.
