Catalysis of the transfer of potassium ions (K+) from one side of a membrane to the other. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + K+(out) = ADP + phosphate + K+(in). Catalysis of the transfer of metal ions from one side of a membrane to the other. Catalysis of the transfer of a inorganic cations with a valency of one from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. Catalysis of the transfer of an ion from one side of a membrane to the other, driven by the reaction: ATP + H2O = ADP + phosphate. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O = ADP + phosphate, to directly drive the transport of ions across a membrane. The reaction is characterized by the transient formation of a high-energy aspartyl-phosphoryl-enzyme intermediate.
