CC   -!- FUNCTION: Facilitates L-arginine uptake, as part of the AaxABC system.
CC       The arginine uptake by the bacterium in the macrophage may be a
CC       virulence factor against the host innate immune response (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the OprB family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAP07021.1; Type=Erroneous initiation; Evidence={ECO:0000305};
