An example of a proton pump that is not electrogenic, is the proton/potassium pump of the gastric mucosa which catalyzes a balanced exchange of protons and potassium ions. [citation needed] The combined transmembrane gradient of protons and charges created by proton pumps is called an electrochemical gradient.
The gastric hydrogen potassium ATPase or H + /K + ATPase is the proton pump of the stomach.It exchanges potassium from the intestinal lumen with cytoplasmic hydronium [2] and is the enzyme primarily responsible for the acidification of the stomach contents and the activation of the digestive enzyme pepsin [3] (see gastric acid).

The proton pump is the terminal stage in gastric acid secretion, being directly responsible for secreting H + ions into the gastric lumen, making it an ideal target for inhibiting acid secretion. [ citation needed ] Because the H,K-ATPase is the final step of acid secretion, an inhibitor of this enzyme is more effective than receptor ...
The AKMSN model is derived from the AKMS and features an accessory rail used to mount a night vision sensor as seen on the AKML and additionally a flash hider and bipod. The left arm of the AKMSN's folding stock is bent outwards in order to avoid the sight mount bracket during folding and the sling loop was moved further to the rear.

Proton pump inhibitors are prodrugs and their actual inhibitory form is somewhat controversial. In acidic solution, the sulfenic acid is isolated before reaction with one or more cysteines accessible from the luminar surface of the enzyme, a tetracyclic sulfenamide. This is a planar molecule thus any enantiomer of a PPI loses stereospecifity ...
