title: The structure of the O-specific chain of lipopolysaccharide from Pseudomonas aeruginosa IID 1008 (ATCC 27584).
abstract: Structural studies were carried out on the O-polysaccharide fraction obtained from the lipopolysaccharide of Pseudomonas aeruginosa IID 1008 (ATCC 27584). The O-polysaccharide comprises L-rhamnose, N-acetyl-D-quinovosamine, N-acetyl-D-galactosaminuronic acid, and N-formyl-D-galactosaminuronic acid. The characterization of oligosaccharide fragments resulting from acid hydrolysis, Smith degradation and alkaline degradation of the O-polysaccharide, together with 1H-NMR and 13C-NMR spectroscopic data of the polysaccharide, led to the following structure for the repeating units: ----3)Rha(alpha 1----4)GalNAcA(alpha 1----4 GalNFoA(alpha 1----3)QuiNAc(alpha 1----. Almost all of the carboxyl groups of the N-acetylgalactosaminuronic acid residues and about half of the same groups of the N-formylgalactosaminuronic acid residues were in an amide form.
