IntEnz Enzyme Nomenclature


Accepted name:
H+-exporting ATPase
Other names:
ATP phosphohydrolase
proton-translocating ATPase
yeast plasma membrane ATPase
yeast plasma membrane H+-ATPase
Systematic name:
ATP phosphohydrolase (H+-exporting)




A P-type ATPase that undergoes covalent phosphorylation during the transport cycle. This enzyme occurs in protozoa, fungi and plants, and generates an electrochemical potential gradient of protons across the plasma membrane.
