Protein
Lipopolysaccharide export system ATP-binding protein LptB
Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Function
Part of the ABC transporter complex LptBFG involved in the translocation of lipopolysaccharide (LPS) from the inner membrane to the outer membrane. Probably responsible for energy coupling to the transport system (By similarity).
Similarity
Belongs to the ABC transporter superfamily. Outer membrane lipopolysaccharide export (TC 1.B.42) family.
