Gram-negative Bacterial Outer Membrane (OM)
- Target
- OM
- Molecular classification
- Lipid Bilayer, Membrane structure, Lipopolysaccharide, Outer Membrane Protein, LPS, OMP
01
Overview
The Gram-negative bacterial outer membrane is a complex structure crucial for protection against environmental threats, maintenance of cellular integrity under stress conditions, mediation of host-pathogen interactions via surface molecules like LPS and OMPs, and conferring significant resistance to many antibiotics through its selective permeability barrier function. Its unique composition—particularly LPS—and biogenesis mechanisms make it both a challenge for clinical treatment strategies and an attractive target for novel antimicrobial development.
