title: Structure of polysaccharide moiety of Pseudomonas xanthomarina KMM 1447Tlipopolysaccharide.
abstract: The structural analysis of a polysaccharide moiety of Pseudomonas xanthomarina KMM 1447Tlipopolysaccharide (LPS) was carried out. Mild acid degradation of LPS resulted in identification of two polysaccharides. The major one was built of β-D-GlcpNAcA residues amidated with L-Ala and Gly residues randomly. The minor polysaccharide was composed of branched tetrasaccharide repeating units constituted by two D-Galр, D-GalpNAc and ether of D-Glc with (2R,4R)-2,4-dihydroxypentanoic acid lactone (2R,4R-Dhpl): →3)-α-D-Galр-(1 → 3)-β-D-Galр-(1 → 3)-[β-D-Glcp4(2R,4R-Dhpl)-(1 → 4)]-β-D-GalpNAc-(1 → .
