Bacterial enzymes and DNA

“Bacterial enzymes and DNA” collectively describes a broad set of bacterial proteins that interact with and modify DNA, including but not limited to DNA gyrase, topoisomerase IV, DNA ligases, and restriction-modification systems. These enzymes are essential for bacterial replication, DNA repair, recombination, and maintenance of DNA topology[6][7][1][5]. Many are critical drug targets in anti-infective therapy (e.g., fluoroquinolones targeting DNA gyrase), while others confer resistance to antibiotics (e.g., β-lactamases). Because this term is not a unique molecular entity but rather a category, it is not suitable as a precise, structured therapeutic target. This entry is best divided into individual, functionally and structurally distinct enzymes (e.g., DNA gyrase, bacterial DNA ligase) for structured target databases.

Inhibition of DNA replication (e.g., by blocking gyrase or topoisomerases[6]); Blocking DNA ligation or recombination (uncommon in therapeutics); Disruption of cell wall synthesis (indirectly DNA-related, via β-lactamase activity[6]); Cleavage of DNA at specific sites (restriction enzymes[5][7])
