CC   -!- FUNCTION: Forms an efflux pump with AaeA. Could function as a metabolic
CC       relief valve, allowing to eliminate certain compounds when they
CC       accumulate to high levels in the cell. {ECO:0000255|HAMAP-
CC       Rule:MF_01545}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01545}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01545}.
CC   -!- INDUCTION: Positively coregulated with aaeA and aaeX by AaeR.
CC       {ECO:0000255|HAMAP-Rule:MF_01545}.
CC   -!- SIMILARITY: Belongs to the aromatic acid exporter ArAE (TC 2.A.85)
CC       family. {ECO:0000255|HAMAP-Rule:MF_01545}.
