Abstract
Staphylococcus aureus uses numerous strategies to survive and persist in the intracellular environment of professional phagocytes, including modulation of the SUMOylation process. This study aims to understand how S. aureus alters host SUMOylation to enhance its intracellular survival in professional phagocytes. Our results indicate that S. aureus strain Newman utilizes PtpA-driven phosphorylation to decrease the amount of SUMOylated proteins in murine macrophages to facilitate its survival in this immune cell type.
