H+/k+ atp pump
WebAnti-parietal cell antibodies (APCA) are an advantageous tool for screening for autoimmune atrophic gastritis (AAG) and pernicious anemia (PA). The target for APCA is the H+/K+ ATP-ase. It has been demonstrated, that APCA target both, the alpha, and beta subunits of the proton pump, although the maj … WebATP synthase can also function in reverse, that is, use energy released by ATP hydrolysis to pump protons against their thermodynamic gradient. Classification. There are different types of ATPases, ... H+/K+ transporting, nongastric: ATP12A; type 13: ATP13A1, ATP13A2, ATP13A3, ATP13A4, ATP13A5; See also. AAA proteins.

Web18 apr 2024 · The gastric proton pump, also known as H+,K+-ATPase, is expressed on the surface of the stomach to secrete the gastric acid indispensable for digestion of proteins in food. However, too much acid secretion induces ulcers. The gastric proton pump uptakes protons from the neutral cytoplasm (pH 7) to the acidic milieu of the stomach (pH 1) … 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.
