Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. Catalysis of the reaction: solute A(out) + solute B(in) = solute A(in) + solute B(out). Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: sulfate(out) + solute(in) = solute(in) + sulfate(out), by a channel in a cell membrane whose opening is governed by the membrane potential. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: succinate(out) + fumarate(in) = succinate(in) + fumarate(out). Catalysis of the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: dicarboxylate(out) + inorganic phosphate(in) = dicarboxylate(in) + inorganic phosphate(out). Catalysis of the transfer of a solute from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Chemiosmotic sources of energy include uniport, symport or antiport. Catalysis of the active transport of a potassium ion across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.
