The structure of the carbohydrate backbone of the LPS from Shewanella putrefaciens CN32 Original Research Article

The lipopolysaccharide (LPS) from a natural rough strain of Shewanella putrefaciens CN32 was analyzed using NMR and mass spectroscopy and chemical methods, and the following structure of its carbohydrate backbone is proposed:β-Galf-(1→3)-β-Gal-(1→4)-β-Glc-(1→4)-α-DDHep2PEtN-(1→5)-α-Kdo4P-(1→6)-β-GlcN4P-(1→6)-α-GlcN1P
