CC   -!- FUNCTION: Part of the ABC transporter complex hrt involved in hemin
CC       import. Responsible for the translocation of the substrate across the
CC       membrane (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (HrtA),
CC       two transmembrane proteins (HrtB) and a solute-binding protein.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ABC-4 integral membrane protein family. HrtB
CC       subfamily. {ECO:0000305}.
