Term Name: antiporter activity
Synonyms: antiport, countertransporter activity, exchange transporter activity, exchanger, ion antiporter activity, porter, solute:solute antiporter activity
Definition: 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. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out).
