  • 相关性Helicobacter pylori is a Gram-negative, microaerophilic bacterium that inhabits various areas of the stomach and duodenum. It causes a chronic low-level inflammation of the stomach lining and is strongly linked to the development of duodenal and gastric ulcers and stomach cancer. Over 80% of individuals infected with the bacterium are asymptomatic. Urease is a heterohexamer of 3 ureA (alpha) and 3 ureB (beta) subunits. Four heterohexamers assemble to form a 16 nm dodecameric complex. It is a nickel-dependent metalloenzyme that catalyzes the hydrolysis of urea to form ammonia and carbon dioxide. The ammonia produced by ureolysis increases the gastric pH thereby providing an environment permissive for colonization of the stomach. The dodecameric complex is active at pH 3.0. The novel dodecameric structure of the enzyme may allow it to remain active at the cell surface at acidic gastric pH. Within this dodecameric structure the 12 active sites are clustered within the interior of the proteinaceous shell. This may allow a high local concentration of ammonia within the enzyme which may protect the nickel-chelating groups from protonation.
