Helicobacter pylori metabolic enzymes

Helicobacter pylori metabolic enzymes are a diverse group of proteins essential for the survival, colonization, and pathogenesis of the bacterium within the harsh, acidic environment of the human stomach. The most prominent enzyme is urease, which neutralizes gastric acid by catalyzing the hydrolysis of urea into ammonia and carbon dioxide, creating a habitable microenvironment for the pathogen [1]. Other critical metabolic targets include carbonic anhydrase, which facilitates pH regulation, and enzymes of the shikimate pathway, which are required for the biosynthesis of essential aromatic amino acids not provided by the host [2]. Additionally, enzymes such as glutamate racemase are vital for cell wall peptidoglycan production, while pyruvate:ferredoxin oxidoreductase (PFOR) is central to anaerobic energy metabolism and serves as the activation site for nitroimidazole drugs [3]. Because many of these metabolic pathways are unique to bacteria or possess structural features distinct from their human counterparts, they are considered high-priority targets for the development of novel, narrow-spectrum antibacterial agents. Targeting these enzymes is a key strategy for eradicating H. pylori infections, thereby reducing the risk of chronic gastritis, peptic ulcers, and gastric adenocarcinoma [4].
