Bacterial intracellular proteins and nucleic acids

Bacterial intracellular proteins and nucleic acids represent a broad category of therapeutic targets essential for bacterial survival, growth, and reproduction. This group includes the bacterial genome (DNA), various forms of RNA, and functional proteins such as enzymes and ribosomes. Antibiotics exert their effects by binding to these specific intracellular components to inhibit critical processes like DNA replication, transcription, and protein synthesis (StatPearls, 2023). For instance, fluoroquinolones target DNA gyrase and topoisomerase IV, while aminoglycosides and tetracyclines target the 30S ribosomal subunit (Nature Reviews Microbiology, 2014). These targets are often chosen for their structural differences from human analogs, allowing for selective toxicity against pathogens (Merck Manual, 2024). However, because this term refers to a wide variety of distinct molecular entities rather than a single receptor or enzyme, it is considered a broad target category in pharmacology (StatPearls, 2023).
