Molinaro, A., Silipo, A., De Castro, C., Sturiale, L., Nigro, G., Garozzo, D., Bemardini, M.L., Lanzetta, R., Parrilli, M. Lull structural characterization of Shigella flexneri M90T serotype 5 wild-type R-LPS and its AgalU mutant glycine residue location in the inner core of the lipopolysaccharide. Glycobiology 18(3) (2008) 260-269. 

The polysaccharide chain of the cell wall lipopolysaccharide of Escherichia coli 058 contains D-mannose, 2-acetamido-2-deoxy-D-mannose, 3-0-[(l R)-carboxyethyl)]-L-rhamnose (rhamnolytic acid), and 0-acetyl groups in the molar ratios of 2 1 1 . Structural investigations show that this polysaccharide, which contains a substituted trisaccharide repeating unit, has an identical structure (4) to that of Shigella dysenteriae type 5. 

A lipopolysaccharide has been isolated from Shigella flexneri, type 2, and some of its structural aspects have been elucidated. ... 

The hexose region of the core polysaccharides of lipopolysaccharides isolated from Shigella flexneri and some Escherichia coli species have a common structure (7). ...
