CC   -!- FUNCTION: Part of the ABC transporter complex LptBFG involved in the
CC       translocation of lipopolysaccharide (LPS) from the inner membrane to
CC       the outer membrane. Probably responsible for energy coupling to the
CC       transport system (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the lipopolysaccharide transport and assembly
CC       complex. The LptBFG transporter is composed of two ATP-binding proteins
CC       (LptB) and two transmembrane proteins (LptF and LptG) (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cell inner membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. Outer membrane
CC       lipopolysaccharide export (TC 1.B.42) family. {ECO:0000305}.
