Bacterial cell membrane and fungal cell membrane

Bacterial and fungal cell membranes are dynamic lipid bilayer structures critical for maintaining cell viability, regulating permeability, and hosting key enzymes for synthesis and energy production. In bacteria, the cytoplasmic membrane includes transport proteins and, in Gram-negative bacteria, is complemented by an outer membrane containing lipopolysaccharides. Fungal cell membranes are characterized by the presence of sterols, particularly ergosterol, phospholipids, and sphingolipids, which serve as drug targets distinct from their mammalian counterparts[2][6][5][7]. Disruption of membrane integrity results in loss of cellular homeostasis, leakage of vital metabolites, and cell death. Drugs targeting these membranes are vital for treating invasive infections. Although well-validated, membranes are complex structures rather than single protein targets, and the term “Bacterial and Fungal Cell Membranes” in this context is non-specific and should ideally be separated for precision[2][4][6].This entry provides the core attributes needed for structured data extraction but should be split into “Bacterial cell membrane” and “Fungal cell membrane” for canonical targeting.

Disruption of membrane integrity via binding to sterols (ergosterol for fungi); Inhibition of sterol biosynthesis (triazoles block ergosterol production in fungi); Increased permeability and leakage of intracellular contents; Direct interaction with membrane phospholipids, causing ion efflux and cell death
