This study identifies multiple non-redundant functions of lipopolysaccharide (LPS) in Gram-negative bacteria, showing it is essential for envelope mechanics, membrane biogenesis, and efflux pump activity.

This study shows that diverse stresses cause periplasmic expansion in E. coli through distinct mechanisms, but UDP-glucose synthesis is required for expansion under some conditions.

This study shows that outer membrane fluidity and mechanics in Gram-negative bacteria can be independently controlled by altering lipid composition and crosslinking.

This paper shows that overproduction of ppGpp in E. coli increases resistance to β-lactam antibiotics targeting PBP2 by enhancing PBP1B activity through LpoB activation.

This study shows that Klebsiella pneumoniae becomes more resistant to beta-lactam antibiotics at low pH due to the activity of specific penicillin-binding proteins.

This study identifies the mechanistic basis of cell-size homeostasis in bacteria, showing it results from threshold accumulation and balanced biosynthesis, and demonstrates how to reprogram this process.

The paper investigates how the charge patterning and sequence complexity of the FtsZ C-terminal tail influence Z-ring formation and bacterial cell division.
