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 ¹H and ¹³C 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.
