    Lipopolysaccharide (LPS), a lipoglycan from the outer membrane of Gram-negative bacteria, is an immunomodulatory molecule that stimulates the innate immune response. High levels of LPS cause excessive release of inflammatory mediators and are responsible for the septic shock syndrome. The interaction of LPS with its cognate binding proteins has not, as yet, been structurally elucidated.
