CC -!- FUNCTION: Major component of the acid-resistance (AR) system allowing
CC enteric pathogens to survive the acidic environment in the stomach.
CC Exchanges extracellular arginine for its intracellular decarboxylation
CC product agmatine (Agm) thereby expelling intracellular protons.
CC Probably undergoes several conformational states in order to
CC translocate the substrate across the membrane; keeps the substrate
CC accessible to only 1 side of the membrane at a time by opening and
CC closing 3 membrane-internal gates. {ECO:0000250|UniProtKB:P60063}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=agmatine(in) + L-arginine(out) = agmatine(out) + L-
CC arginine(in); Xref=Rhea:RHEA:29651, ChEBI:CHEBI:32682,
CC ChEBI:CHEBI:58145; Evidence={ECO:0000250|UniProtKB:P60061};
CC -!- SUBUNIT: Homodimer; each subunit has its own individual transport
CC capacity. {ECO:0000250|UniProtKB:P60061}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:P60061}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- DOMAIN: Each subunit has 12 transmembrane (TM) helices; TM1 and TM6 are
CC interrupted by short non-helical Gly-rich loops in the middle of their
CC transmembrane spans. Each subunit has a central cavity which binds
CC substrate. {ECO:0000250|UniProtKB:P60061}.
CC -!- SIMILARITY: Belongs to the amino acid-polyamine-organocation (APC)
CC superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2)
CC family. {ECO:0000305}.
