Structural analysis of the lipopolysaccharide from Neisseria meningitidis strain BZ157 galE: localisation of two phosphoethanolamine residues in the inner core oligosaccharide.

Abstract excerpt

The structure of the phase-variable lipopolysaccharide (LPS) from the group B Neisseria meningitidis strain BZ157 galE was elucidated. The structural basis for the LPS's variation in reactivity with a monoclonal antibody (MAb) B5 that has specificity for the presence of phosphoethanolamine (PEtn) at the 3-position of the distal heptose residue (HepII) was established. The structure of the O-deacylated LPS was...
