Bacterial Cell Membrane and Associated Proteins

The bacterial cell membrane, composed of a phospholipid bilayer and associated proteins, is essential for bacterial survival. It mediates transport, energy generation, and response to environmental stressors. Heavy metals, like bismuth, disrupt membrane integrity and protein function by binding to key proteins and lipids, leading to antimicrobial effects. Bacteria employ defense mechanisms like metal-binding proteins and efflux pumps to counteract this toxicity. Targeting the bacterial cell membrane and associated proteins is a viable antimicrobial strategy, but resistance mechanisms must be considered.
