Structural determination of the O-specific chain of the lipopolysaccharide from the mushrooms pathogenic bacterium Pseudomonas tolaasii

摘要

The complete structure of the O-specific polysaccharide of the lipopolysaccharide isolated from the cultivated mushrooms pathogen Pseudomonas tolaasill is described.The structural determination achieved by chemical and spectroscopical analyses indicates a novel tetrasaccharide repeating unit built up to two units of 2-acetamido-2,6-di-deoxy-glucopyranose (Quinovosamine,QuiNAc) and two units of 2-acetamido-2-deoxy-gulopyranuronamide (Gulp NAcAN)one of which is acetylated at C-3 position
