title: The structure of the O-specific polysaccharide from marine bacterium Litorimonas taeanensis G5T containing 2-acetamido-4-((3S,5S)-3,5-dihydroxyhexanamido)-2,4-dideoxy-D-quinovose and 2-acetamido-2,6-dideoxy-L-xylo-hexos-4-ulose.
abstract: The O-polysaccharide was isolated from the lipopolysaccharide of Litorimonas taeanensis G5(T) and studied by chemical methods along with (1)H and (13)C NMR spectroscopy, including (1)H, (1)H COSY, 1D and 2D TOCSY, NOESY, (1)H, (13)C HSQC, HMBC, and H2BC experiments. The following new structure of the O-polysaccharide of L. taeanensis G5(T) containing 2-acetamido-2-deoxy-D-galacturonic acid (D-GalNAcA), 2-acetamido-4-((3S,5S)-3,5-dihydroxyhexanamido)-2,4-dideoxy-D-quinovose (D-QuiNAc4NR), and 2-acetamido-2,6-dideoxy-L-xylo-hexos-4-ulose (L-Sug) was established: →4)-α-D-GalpNAcA-(1→3)-α-D-QuiNAc4NR-(1→3)-α-L-Sug-(1→ where R is (3S,5S)-3,5-dihydroxyhexanoic acid.
