Structure of the O-polysaccharide of Pragia fontium 27480 containing 2,3-diacetamido-2,3-dideoxy-d-mannuronic acid.
The following structure of the O-polysaccharide of Pragia fontium 27480 was elucidated by sugar analysis, including determination of the absolute configurations of the monosaccharides, and Smith degradation along with 1D and 2D (1)H and (13)C NMR spectroscopy: →4)-β-d-ManpNAc3NAcA-(1→2)-α-l-Rhap-(1→3)-β-l-Rhap-(1→4)-α-d-GlcpNAc-(1→ where ManNAc3NAcA stands for 2,3-diacetamido-2,3-dideoxymannuronic acid.
