Staphylococcus aureus GpsB, Stk, and VraSR form a cell wall surveillance network to maintain cell envelope integrity and mediate antibiotic resistance

This study identifies GpsB, Stk, and VraSR as forming a cell wall surveillance network in S. aureus that maintains cell envelope integrity and contributes to antibiotic resistance.

Magnesium induces iron starvation and metabolic rewiring to support the viability of cell envelope mutants and antibiotic-stressed cells

This paper shows magnesium reduces iron availability and redirects metabolism to mitigate oxidative stress in cell envelope mutants and antibiotic-stressed cells.

GpsB is an accessory Z-ring anchor

This paper identifies GpsB as an accessory Z-ring anchor in Bacillus subtilis and shows its interaction with FtsZ through a conserved R-X-X-R motif in several Firmicutes species.
