Helicobacter pylori enzymes and structural proteins (H. pylori proteins)

Helicobacter pylori enzymes and structural proteins encompass a wide array of bacterial components necessary for the organism's persistence in the acidic human stomach. The most prominent enzyme, urease, catalyzes the hydrolysis of urea into ammonia and carbon dioxide, effectively neutralizing local gastric acid to allow bacterial survival (StatPearls, 2023). Structural proteins, including those forming the flagella and the Type IV secretion system, facilitate motility and the injection of virulence factors like CagA into host cells (Nature Reviews Microbiology, 2023). These proteins are targeted by various therapeutic agents; for instance, beta-lactams target penicillin-binding proteins involved in cell wall synthesis, while macrolides inhibit the 50S ribosomal subunit to halt protein production (PubChem, 2024). Eradication of these targets is the standard of care for treating chronic gastritis, peptic ulcers, and reducing the risk of gastric adenocarcinoma (NIH, 2023). However, the rapid emergence of multi-drug resistant strains remains a critical barrier to successful clinical outcomes (WHO, 2024).
