Proton Pump Inhibitors

A proton pump plays a key role in cell respiration as a specical membrane protein. A proton pump includes (H+/K+ ATPase) the gastric hydrogen potassium ATPase which is the proton pump of the stomach. The gastric H+,K+-ATPase, which is responsible for gastric acid secretion, is a P2-type ATPase located in the apical membrane of parietal cells. The enzyme is an α/β heterodimer. The α subunit, which has cation-binding and ATP-binding sites, plays a crucial role in catalytic activity. The β subunit is responsible for functional expression.
