Bacterial cell membranes and metabolic enzymes

Bacterial cell membranes and metabolic enzymes represent a broad category of therapeutic targets essential for the survival, growth, and reproduction of prokaryotic organisms. The bacterial cell membrane serves as a critical semi-permeable barrier and a site for energy transduction, which can be disrupted by lipopeptide and polymyxin antibiotics to cause rapid loss of membrane potential and cell death (StatPearls, 2023). Metabolic enzymes, such as those involved in the folic acid synthesis pathway (e.g., dihydropteroate synthase) or DNA replication (e.g., DNA gyrase), are vital for maintaining cellular homeostasis and genetic integrity (PubMed, 2021). Targeting these components allows for selective toxicity against bacterial pathogens while ideally sparing host cells. However, because this term encompasses a wide variety of distinct molecular targets, it is generally categorized as a target class rather than a single therapeutic target. Resistance mechanisms, such as membrane modification or enzymatic mutations, pose significant challenges to drugs hitting these targets (NIH, 2022).
