Bacterial intracellular enzymes

Bacterial intracellular enzymes encompass a vast array of catalytic proteins located within the bacterial cytoplasm that are vital for maintaining cellular homeostasis and driving growth. These enzymes are involved in fundamental biological pathways, including nucleic acid synthesis, protein translation, and intermediary metabolism, making them highly effective targets for antimicrobial therapy [1][2]. Key examples include DNA gyrase and Topoisomerase IV, which are targeted by quinolones to disrupt DNA replication, and RNA polymerase, the target of rifamycins [3][4]. Other critical enzymes include those in the folate synthesis pathway, such as dihydropteroate synthase and dihydrofolate reductase, which are inhibited by sulfonamides and trimethoprim, respectively [5]. The therapeutic strategy relies on the structural divergence between bacterial enzymes and their human counterparts to achieve selective toxicity [6]. Despite their success, the effectiveness of targeting these enzymes is constantly threatened by the evolution of resistance mechanisms, such as target modification and the production of bypass enzymes [7].
