Descriptions

The plasma membrane H+-ATPase belongs to the superfamily of P-type ATPases. The H+-ATPase is responsible for the ATP-fuelled ejection of protons from the cell and is an important component in the generation of the trans-membrane H+ gradient in plant cells. The H+-ATPase AHA2 is controlled by an autoinhibitory C-terminal regulatory domain and activated by 14-3-3 proteins which bind to the part of the enzyme. In two regions of the C-terminus, alteration of the residues leads to increased pump activity. One region stretches from K863 to L885 and includes two residues (Q879 and R880) that are conserved between plant and fungal H+-ATPases. The other region, incorporating S904 to L919, is situated in an extension of the C-terminus unique to plant H+-ATPases.
