A phosphorylated O-specific polysaccharide was obtained by mild acidic degradation of the lipopolysaccharide from the enteric bacterium Escherichia coli O130 and characterized by the methods of chemical analysis, including dephosphorylation and 1H and 13C NMR spectroscopy. The polysaccharide was shown to be composed of branched tetrasaccharide repeating(More)
Snakes have numerous features distinctive from other tetrapods and a rich history of genome evolution that is still obscure. Here, we report the high-quality genome of the five-pacer viper, Deinagkistrodon acutus, and comparative analyses with other representative snake and lizard genomes. We map the evolutionary trajectories of transposable elements (TEs),(More)
The structure of the O-polysaccharide (O-antigen) from Shigella dysenteriae type 8 bacteria (strain 599) was corrected using modern NMR techniques (structure 1). The revisions concerned the position of the Glc residue (in the main, but not the side chain), the site of its substitution, and the configuration of the O-glycoside linkage of the GlcNAc residue.(More)
The reported structures of O-specific polysaccharides from three type strains of Shigella bacteria were corrected by modern NMR techniques. The revisions concerned the configuration of the O-glycoside linkage (S. dysenteriae type 3, structure 1), the positions of monosaccharide residue glycosylation and acetalation by pyruvic acid (S. dysenteriae type 9,(More)
