The cell envelope of Staphylococcus aureus selectively controls the sorting of virulence factors

Abstract

The pathogen Staphylococcus aureus releases several pore-forming toxins, termed leukocidins, that kill immune cells. Here, Zheng et al. show that the retention of a leukocidin on bacterial cells and its release are modulated by lipoteichoic acid and a membrane lipid, which also control the sorting of other surface-associated proteins.
