title: O-specific polysaccharide of Hafnia alvei lipopolysaccharide isolated from strain 1211. Structural study using chemical methods, gas-liquid chromatography/mass spectrometry and NMR spectroscopy.
abstract: The Hafnia alvei strain 1211 O-specific polysaccharide is composed of 3-amino-N-(D-3'-hydroxybutyryl)-3,6-dideoxy-D-galactose, N-acetyl-D-galactosamine, N-acetyl-D-glucosamine and D-glucose (1:1:2:2). On the basis of sugar and methylation analyses, Smith degradation, and one- and two-dimensional 1H- and 13C-NMR spectroscopy, the polysaccharide was shown to be an O-acetylated polymer of the repeating hexasaccharide unit, ----2D(4-OAc)Fucp3NAcyl beta 1----6DGlcpNAc alpha 1---- (DGlcp beta 1----3)4DGalpNAc alpha 1----3DGlcpNAc beta 1----2DGlcp beta 1----, where DFucp3NAcyl = 3-amino-N-(D-3'-hydroxybutyryl)-3,6-dideoxy-D- galactopyranose. The O-specific polysaccharide showed some microheterogeneity due to incomplete substitution by terminal glucose.
