Lm. Beynon et Mb. Perry, STRUCTURE OF THE LIPOPOLYSACCHARIDE O-ANTIGEN OF PSEUDOMONAS-CEPACIA SEROTYPE-A, Biochemistry and cell biology, 71(9-10), 1993, pp. 417-420
The O-antigenic polysaccharides of the lipopolysaccharides produced by
three isolates of Pseudomonas cepacia serogroup A were analysed by co
mposition, methylation, periodate oxidation, and two-dimensional nucle
ar magnetic resonance methods. They were found to be identical linear
unbranched polymers of a repeating trisaccharide unit containing 2-ace
tamido-2-deoxy-D-galactose and L-rhamnose residues (2:1) and have the
structure [-->3)-alpha-D-GalpNAc-(l --> 3)-beta-D-GalpNAc-(l -->4)-alp
ha-L-Rhap-(l -->](n)
