title: The structure of the polysaccharide produced by Proteus vulgaris (ATCC 49990).
abstract: An exocellular polysaccharide produced by a clinical isolate of Proteus vulgaris (ATCC 49990) was shown by composition, methylation, periodate oxidation, and nuclear magnetic resonance analyses to be composed of repeating trisaccharide units containing D-galactose, 2-acetamido-2-deoxy-D-glucose and pyruvic acid (2:1:1), and having the structure: [formula: see text] The homologus smooth lipopolysaccharide of the P. vulgaris strain was determined to have an O-polysaccharide component having the same structure as the above extracellular polysaccharide.
