Other Helicobacter pylori enzymes

Other Helicobacter pylori enzymes is a collective term for a diverse group of enzymatic targets within the bacterium Helicobacter pylori, excluding the primary target urease. This category includes enzymes essential for bacterial survival, such as those involved in cell wall biosynthesis (e.g., penicillin-binding proteins and glutamate racemase), nucleic acid metabolism (e.g., DNA gyrase and RNA polymerase), and protein synthesis (e.g., peptide deformylase) (PubMed, UniProt). These enzymes allow the bacterium to maintain structural integrity, replicate its genome, and adapt to the highly acidic environment of the human stomach (StatPearls). Clinically, these enzymes are the targets of various antibiotics used in eradication regimens, such as amoxicillin, which inhibits cell wall synthesis enzymes, and levofloxacin, which targets DNA gyrase (StatPearls). The inhibition of these other enzymes is critical for treating H. pylori-related diseases, including chronic gastritis, peptic ulcers, and gastric adenocarcinoma (NIH). However, the therapeutic utility of targeting these enzymes is increasingly challenged by the development of antibiotic resistance, often mediated by specific mutations in the target enzymes themselves, such as mutations in the gyrA gene or the 23S rRNA component of the translation machinery (PubMed, WHO).
