Helicobacter pylori cell wall integrity protein (or Helicobacter pylori outer membrane)

The cell wall and outer membrane of Helicobacter pylori, a Gram-negative bacterium, are essential for survival, pathogenicity, and antibiotic resistance. Critical components include lipopolysaccharide (LPS), outer membrane proteins, and unique cholesterol glucosides that maintain morphology and barrier function. Disruption of membrane integrity—whether via direct physical action (as with certain antibiotics, antimicrobial peptides, or lipo-fatty acids) or interference with biosynthetic pathways—leads to increased permeability, leakage of cytoplasmic contents, and rapid bacterial death. Such interventions target the bacteria’s protective barriers and can enhance the effects of other antibiotics. However, there is no single "membrane integrity protein"; this target describes a strategic vulnerability in H. pylori, not a specific gene product.

Other names

H. pylori outer membraneH. pylori cell wallH. pylori membrane integrity

Disruption of the bacterial cell wall/membrane, increasing permeability and causing leakage of cellular contents, resulting in cell death. Direct insertion and perturbation of membrane lipids. Destabilization or loss of LPS (lipopolysaccharide), a component crucial for Gram-negative bacterial membrane integrity.
