[Chemical composition of the Pseudomonas solanecearum lipopolysaccharide].

The structure of Pseudomonas solanacearum lipopolysaccharide is similar to those described for the LPS of enterobacteria. The lipid A contains fatty acids and glucosamine (5 fatty acids for 2 glucosamine residues). The polysaccharide part contains 2-keto-3-deoxy-octulosonate, L-glycero-D-mannoheptose, hexoses (glucose, rhamnose, glucosamine) and a pentose (xylose). Part of 3-hydroxy-myristic acid and the whole 2-hydroxy-octadecenoïc acid are linked to the glucosamine residue by an amide bond.
