Structure of a teichoic acid-like O-polysaccharide of Escherichia coli O29.
A teichoic acid-like O-polysaccharide was isolated by mild acid degradation of the lipopolysaccharide (LPS) of Escherichia coli O29. The O-polysaccharide and an oligosaccharide obtained by dephosphorylation of the O-polysaccharide were studied by sugar analysis along with 1H and 13C NMR spectroscopy. The following structure of the branched oligosaccharide repeating unit, containing five monosac...
متن کاملThe structure of the capsular polysaccharide from a swarming strain of pathogenic Proteus vulgaris.
The structure was determined for the capsular polysaccharide (CPS) isolated from a swarming strain of Proteus vulgaris, CP2-96, which was obtained from the spleen of an infected mouse. The CPS was extracted from the cell pellet by hot water, precipitated with ethanol, and further purified by gel-permeation chromatography. The structure was established by glycosyl composition and linkage analyse...
متن کاملStructure of the O-specific polysaccharide of Proteus penneri strain 41 from a new proposed serogroup O62.
O-specific polysaccharide of Proteus penneri strain 41 was studied using 1H- and 13C-NMR spectroscopy, including two-dimensional COSY, heteronuclear 13C,1H-correlation (HETCOR) and one-dimensional NOE spectroscopy, and the following structure of a non-stoichiometrically O-acetylated hexasaccharide repeating unit was established:[structure: see text] where RGlcNAc is 2-acetamido-4-O-[(S)-1-carbo...
متن کاملThe glycerol teichoic acid of walls of Staphylococcus lactis I3.
1. The teichoic acid from walls of Staphylococcus lactis I3 was isolated by extraction with trichloroacetic acid and shown to contain glycerol, N-acetylglucosamine, phosphate and d-alanine in the molecular proportions 1:1:2:1. The alanine is attached to the polymer through ester linkages. 2. Hydrolysis with acid gave alanine, glucosamine and glycerol diphosphates. Under mild acid conditions a r...
متن کاملThe glycerol teichoic acid from walls of Staphylococcus epidermidis I2.
1. Walls of Staphylococcus epidermidis I2 contain 30% (w/w) of a glycerol teichoic acid containing phosphate, d-alanine and d-glucose in the molecular proportions 1:0.25:0.50. 2. The teichoic acid was isolated by extraction with trichloroacetic acid and with dilute aqueous NN-dimethylhydrazine at pH7, and was shown to be a (1-->3)-linked poly(glycerol phosphate) containing beta-d-glucopyranosyl...
