Structure of a teichoic acid-like O-polysaccharide of Escherichia coli O29.
نویسندگان
چکیده
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 monosaccharide residues and glycerol 1-phosphate (D-Gro-1-P), was established: [carbohydrate structure: see text].

Structure of the Escherichia coli K2 capsular antigen, a teichoic acid-like polymer.
The primary structure of the K2 antigen of Escherichia coli was elucidated by composition, alkaline fragmentation, dephosphorylation with hydrofluoric acid, periodate oxidation, and methylation analysis. The polymer contains galactose in the pyranosidic and furanosidic ring form. It consists of phosphogaolactopyranosyl glycerol and phosphagalactofuranosyl glycerol units in a molar ratio of 2:1....
متن کاملPurification and evaluation of glycerol teichoic acid from biofilm forming Staphylococcus epidermidis as a putative vaccine candidate
Introduction: Biofilm forming Staphylococcus epidermidis is a main causative agent of infections related to medical devices. Purification and evaluation of Gly-TA polysaccharide from a biofilm-forming S. epidermidis as a putative vaccine candidate were the main goals of the current study. Methods: Taking advantage of size exclusion chromatography procedure, glycerol teichoic acid (Gly-TA) was p...

Abstract Background and objectives: important virulence factor for many invasive bacterial pathogens of humans. Escherichia coli offer a model system to study the mechanisms by which capsular polysaccharides are synthesized and exported onto the cell surface of bacteria. Biosynthesis of the E consists of the repeat structure -4) GlcA- (1, 4)-GlcNAc- (1-, requires the KfiA,...
متن کاملVirulence factors and biochemical characteristics of serotypes of Escherichia coli serogroup O29.
Escherichia coli strains belonging to serogroup O29 were studied. Invasiveness was the most common virulence factor described in this serogroup, but a few papers also reported production of heat-stable (ST) enterotoxin. In the present study invasive ability was found in O29:H- strains, whereas production of ST-I enterotoxin was observed only in serotype O29:H21 strains, showing that virulence w...

An acidic O-polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of Escherichia coli O150 and studied by sugar and methylation analyses, triflic acid solvolysis, Smith degradation, (1)H and (13)C NMR spectroscopy, including 2D ROESY, (1)H,(13)C HSQC, HMQC-TOCSY, and HMBC experiments. The polysaccharide was found to contain a regioisomer of N-acetylisomuramic acid, 2-ac...
