UniProtKB description: Major component of the acid-resistance (AR) system allowing enteric pathogens to survive the acidic environment in the stomach (Probable). Exchanges extracellular arginine for its intracellular decarboxylation product agmatine (Agm) thereby expelling intracellular protons (PubMed:19578361). Probably undergoes several conformational states in order to translocate the substrate across the membrane; keeps the substrate accessible to only 1 side of the membrane at a time by opening and closing 3 membrane-internal gates (By similarity).
