Soluble CD14 (sCD14) is a serum glycoprotein that binds to the Lipid A moiety of lipopolysaccharides (LPS) with high affinity as part of the innate immune response to bacterial endotoxins. In order to investigate structural interactions of Lipid A with sCD14, we have prepared an isotopically labeled form of a fully active and chemically defined endotoxin, Kdo2–Lipid A, which allowed us to carry out detailed NMR spectral mapping of this agonist ligand bound to sCD14 and identify for the first time structural regions that are strongly affected during complex formation with sCD14. These map to two adjacent areas comprising the lower portions of the sugar headgroup and upper half of the acyl chains I, III, and V, which are spatially proximal to the 1- and 4′-phosphate ends. Additionally, we have detected for the first time, presence of differential dynamic behavior for the affected resonances, suggesting a likely role for dynamics in the mechanism of Lipid A pattern recognition by sCD14.
