Accepted name: H+-exporting ATPase
Reaction: ATP + H2O + H+in = ADP + phosphate + H+out
Other name(s): proton-translocating ATPase; yeast plasma membrane H+-ATPase; yeast plasma membrane ATPase; ATP phosphohydrolase
Systematic name: ATP phosphohydrolase (H+-exporting)
Comments: 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.
