Structural analysis of Francisella tularensis lipopolysaccharide.
The structure of the lipid A and core region of the lipopolysaccharide (LPS) from Francisella tularensis (ATCC 29684) was analysed using NMR, mass spectrometry and chemical methods. The LPS containsExpand

Involvement of waaY, waaQ, andwaaP in the Modification of Escherichia coliLipopolysaccharide and Their Role in the Formation of a Stable Outer Membrane*
The waaY, waaQ, andwaaP genes are located in the central operon of thewaa (formerly rfa) locus on the chromosome ofEscherichia coli. This locus contains genes whose products are involved in theExpand

Improved techniques for the preparation of bacterial lipopolysaccharides.
Liopolysaccharides were prepared from six organisms by the use of two cell-disruption procedures before conventional phenol-water extraction. Disruption of cells by grinding with glass beads or byExpand

The Activity of a Putative Polyisoprenol-linked Sugar Translocase (Wzx) Involved in Escherichia coli O Antigen Assembly Is Independent of the Chemical Structure of the O Repeat*
During O antigen lipopolysaccharide (LPS) synthesis in bacteria, transmembrane migration of undecaprenylpyrophosphate (Und-P-P)-bound O antigen subunits occurs before their polymerization andExpand

Structures of Lipopolysaccharides from Klebsiella pneumoniae
Deamination of LPSs from Klebsiella pneumoniae released O-chain polysaccharides together with a fragment of the core oligosaccharide. The structures of the products from serotypes O1, O2a, O2a,c, O3,Expand

Structural and Genetic Analyses of O Polysaccharide from Actinobacillus actinomycetemcomitans Serotype f
ABSTRACT The oral bacterium Actinobacillus actinomycetemcomitans is implicated as a causative agent of localized juvenile periodontitis (LJP). A. actinomycetemcomitans is classified into fiveExpand

Structural characterization of the lipopolysaccharide O antigens of Burkholderia pseudomallei.
A serologically typical strain of Burkholderia pseudomallei (strain 304b) was found to produce two S-type lipopolysaccharides (LPS) differing in the chemical structures of their O-polysaccharideExpand

Involvement of the rml locus in core oligosaccharide and O polysaccharide assembly in Pseudomonas aeruginosa.
L-Rhamnose (L-Rha) is a component of the lipopolysaccharide (LPS) core, several O antigen polysaccharides, and the cell surface surfactant rhamnolipid of Pseudomonas aeruginosa. In this study, fourExpand

Structure of the O-chain of the phenol-phase soluble cellular lipopolysaccharide of Yersinia enterocolitica serotype O:9.
The phenol-phase soluble cellular lipopolysaccharide isolated by the phenol/water extraction method from Yersinia enterocolitica serotype O:9 cells was shown by hydrolytic, periodate oxidation,Expand
