As an ion pump the H + /K + ATPase is able to transport ions against a concentration gradient using energy derived from the hydrolysis of ATP. Like all P-type ATPases, a phosphate group is transferred from adenosine triphosphate (ATP) to the H + /K + ATPase during the transport cycle. Visualizza altro Gastric hydrogen potassium ATPase, also known as H /K ATPase, is an enzyme which functions to acidify the stomach. It is a member of the P-type ATPases, also known as E1-E2 ATPases due to its two states. Visualizza altro The H /K ATPase is a heterodimeric protein, the product of 2 genes. The gene ATP4A encodes the H /K ATPase α subunit, and is a ~1000-amino acid protein that contains … Visualizza altro Inhibiting the hydrogen potassium pump to decrease stomach acidity has been the most common method of treating diseases including gastroesophageal reflux disease (GERD/GORD) … Visualizza altro • Discovery and development of proton pump inhibitors • Solvated electron Visualizza altro 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 and is the enzyme primarily responsible for the acidification of the stomach contents and … Visualizza altro H /K ATPase is a P2-type ATPase, a member of the eukaryotic class of P-type ATPases. Like the Ca and the Na /K ATPases, the H /K ATPase functions as an α, β protomer. Unlike other eukaryotic ATPases, the H /K ATPase is electroneutral, … Visualizza altro • Yao X, Forte JG (2003).

They are found in the membranes of many cells, and especially in those of the nephron of the kidney, specifically in the intercalary cells of the collecting duct and in the epithelial cells of the proximal convoluted tubule. The membrane pump is primarily responsible for maintaining homeostasis of pH and sodium. Defects in Na+/H+ antiporters may result in heart or kidney failure. Angiotensin II upregulates this antiporter in the proximal convoluted tubule in order to promote N… dr flandry mount pleasant sc
