BPI/LBP/CETP domain; Bactericidal permeability-increasing protein (BPI) / Lipopolysaccharide-binding protein (LBP) / Cholesteryl ester transfer protein (CETP) domain; binds to and neutralizes lipopolysaccharides from the outer membrane of Gram-negative bacteria.; Apolar pockets on the concave surface bind a molecule of phosphatidylcholine, primarily by interacting with their acyl chains; this suggests that the pockets may also bind the acyl chains of lipopolysaccharide.
