WebJun 12, 2024 · Background: The pH of the human gastric mucosa varies around 2.5 so that only bacteria with strong acidic stress tolerance can colonize it. The ulcer causing Helicobacter pylori thrives in the gastric mucosa. We analyse the roles of the key outer membrane protein OMPLA in its roles in acid tolerance. WebJun 25, 2024 · These measurements demonstrated that the addition of 5 mM urea has little effect on the periplasmic pH at a medium pH higher than pH 6.5 but rapidly increases the periplasmic pH to pH 6.1 at an acidic medium pH (pH 5.0), corresponding to the opening of the proton-gated channel, UreI, and confirming the basis of gastric colonization. lorazepam 1mg scored tablets
