Escherichia coli K-12 substr. MG1655 Gene-Ontology-Terms Class: GO:0015297 - antiporter activity

Synonyms: GO:0015300, countertransporter activity, exchange transporter activity, 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).

GO:0015298 - solute:cation antiporter activity (21),
GO:0015301 - anion:anion antiporter activity (4),
