Hydrogen potassium ATPase

  • CAS Number: 9000-83-3

Proton - potassium pump or H / K ATPase is an enzyme in the parietal cells in the stomach, which accomplished the transport of protons out of the cells and at the same time of potassium ions into the cell. This ATP is consumed, so it is a so-called membrane-bound ATPase. Be of the cell now additionally negative chloride ions are transported to the same side, they form with the protons there hydrochloric acid ( HCl). So the required hydrochloric acid to kill germs and preparation of the nutrients produced for digestion in the stomach.

The transport equation is:

Inhibitors

Inhibitors of the proton - potassium pump are referred to as proton pump inhibitors.
