label: P-type proton-exporting transporter activity
label_lc: p-type proton-exporting transporter activity
description: "Enables the transfer of protons from one side of a membrane to the other according to the reaction: ATP + H2O + H+(in) = ADP + phosphate + H+(out). These transporters use a phosphorylative mechanism, which have a phosphorylated intermediate state during the ion transport cycle."
