title: Structure of an acidic polysaccharide isolated from Psychrobacter maritimus 3pS containing a bacillosamine derivative.
abstract: An acidic polysaccharide was obtained from Psychrobacter maritimus 3pS isolated from a Siberian cryopeg sample (Kolyma lowland). The following structure of the tetrasaccharide repeating unit of the polysaccharide was established by sugar analysis along with (1)H and (13)C NMR spectroscopy: →2)-α-L-Rhap-(1→4)-α-D-GalpNAcA-(1→3)-α-D-QuipNAc4NHb-(1→3)-β-D-QuipNAc4NHb-(1→ where D-GalNAcA indicates 2-acetamido-2-deoxy-D-galacturonic acid and d-QuiNAc4NHb indicates 2-acetamido-2,4,6-trideoxy-4-[(S)-3-hydroxybutanoyl]amino-D-glucose.
