Microbial enzymes involved in DNA and protein synthesis

Microbial enzymes involved in DNA and protein synthesis represent a broad class of essential proteins required for the growth, survival, and reproduction of pathogens such as bacteria, fungi, and viruses (StatPearls, 2023). This category includes critical enzymes like DNA gyrase and topoisomerase IV, which facilitate DNA unwinding and replication, as well as RNA polymerase, which is central to the transcription of genetic information (PubMed, 2021). Furthermore, the machinery of the ribosome—while a complex of RNA and proteins—serves as the site for protein synthesis and is the target of several major antibiotic classes like macrolides and aminoglycosides (Merck Manual, 2024). These enzymes are highly conserved within microbial species but often possess structural differences from human homologs, allowing for selective toxicity (NIH, 2022). Drugs targeting these pathways are fundamental to treating infectious diseases, though their efficacy is increasingly challenged by the emergence of antimicrobial resistance (WHO, 2023).

Inhibition of DNA topoisomerases (gyrase and topoisomerase IV) to prevent DNA replication; inhibition of RNA polymerase to block transcription; binding to 30S or 50S ribosomal subunits to inhibit protein translation; and inhibition of metabolic enzymes like dihydrofolate reductase to prevent nucleotide synthesis (StatPearls, 2023; Merck Manual, 2024).
