Microbial cell wall and membrane proteins, lipids, and nucleic acids

Microbial cell walls, membranes, and nucleic acids constitute the fundamental structural and genetic framework of bacteria, fungi, and viruses. The cell wall provides mechanical strength and protects against osmotic pressure, while the cytoplasmic membrane acts as a selective barrier for transport and signaling (NIH, 2023). Nucleic acids, including DNA and RNA, are essential for the storage and expression of genetic information required for microbial survival and reproduction (StatPearls, 2024). These components are the primary targets for the majority of existing antimicrobial therapies, which exploit the biochemical differences between microbial and host cells to achieve selective toxicity. For instance, beta-lactam antibiotics disrupt peptidoglycan synthesis in the cell wall, while polyenes target fungal membrane ergosterol, and quinolones inhibit DNA replication enzymes (Nature Reviews Microbiology, 2021). Despite their clinical utility, the emergence of resistance mechanisms and the potential for off-target effects on the human microbiome remain significant therapeutic challenges (PubMed, 2022).
