Bacterial processes

"Bacterial processes" is a broad functional category referring to the essential biological activities and biochemical pathways required for the growth, maintenance, and reproduction of bacterial cells [1, 4]. These processes include cell wall biosynthesis, DNA replication, RNA transcription, and protein translation, which are the fundamental mechanisms targeted by nearly all classes of antibiotics [6, 11]. Because many of these processes involve enzymes or structural assemblies unique to prokaryotes—such as the 30S and 50S ribosomal subunits or penicillin-binding proteins (PBPs)—drugs can selectively inhibit bacteria without significantly affecting human cells [4, 9]. However, the term does not represent a single molecular target or receptor; rather, it encompasses a diverse collection of discrete targets like enzymes (e.g., DNA gyrase), ribosomes, and transporters [6, 10]. In clinical practice, the therapeutic focus on these processes is complicated by the rise of antimicrobial resistance (AMR), where pathogens evolve to bypass or modify these essential pathways to survive drug exposure [3, 8].

Antibiotics target these processes by inhibiting essential steps in bacterial physiology, such as peptidoglycan synthesis in the cell wall, translation at the 30S or 50S ribosomal subunits, and DNA replication via topoisomerase inhibition.
