Structural studies of the O-antigen of the lipopolysaccharide from an avirulent strain (M4S) of Pseudomonas solanacearum.
The structure of the O-antigen of the lipopolysaccharide from an avirulent strain (M4S) of Pseudomonas solanacearum has been investigated by methylation analysis, n.m.r. spectroscopy, and N-deacetylation-deamination, followed by analysis and controlled Smith-degradation of the product. These studies demonstrate that the O-antigen is composed of a tetrasaccharide repeating-unit having the following structure: ----3)-alpha-D-GlcpNAc-(1----2)-alpha-L-Rhap-(1----2)-alpha- L-Rhap-(1----3)- alpha-L-Rhap-(1----.
