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. {ECO:0000256|ARBA:ARBA00024818}.
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).
CC {ECO:0000256|ARBA:ARBA00026081}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000256|ARBA:ARBA00004515}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004515}; Cytoplasmic side
CC {ECO:0000256|ARBA:ARBA00004515}. Cytoplasm
CC {ECO:0000256|ARBA:ARBA00004496}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Outer membrane
CC lipopolysaccharide export (TC 1.B.42) family.
CC {ECO:0000256|ARBA:ARBA00010865}.
