Helicobacter pylori nickel binding protein

摘要

The application discloses a nickel binding protein and its encoding DNA isolated from Helicobacter pylori. This organism is the primary cause of chronic gastritis and ensuing peptic ulcers, and has been implicated in stomach cancer. The nickel binding protein is useful to inhibit assembly of active ureases, the enzymes responsible for the pathogenic features of the bacterium. Potential uses include as a vaccine, a diagnostic, a drug target, and a therapy in itself.
