Independent tuning of outer membrane fluidity and mechanics in Gram-negative bacteria

The outer membrane (OM) of Gram-negative bacteria forms a protective barrier that combines selective permeability with mechanical load-bearing capacity, properties linked to its asymmetric bilayer structure with lipopolysaccharides (LPS) in the outer leaflet and phospholipids (PLs) in the inner leaflet. Unlike most PL...

LPS in Gram-negative bacterial growth and physiology: outside but fully integrated

SUMMARY For single-celled organisms, the cell envelope is the thin barrier between life and death, responding dynamically to both the ever-expanding self and the ever-changing environment. Failure to balance these responses can lead to disastrous consequences, such as lysis. In gram-negative bacteria, the cell envelope...
