STRUCTURE OF THE O-SPECIFIC POLYSACCHARIDE, CONTAINING A GLYCEROL PHOSPHATE SUBSTITUENT, OF HAFNIA ALVEI STRAIN 1220 LIPOPOLYSACCHARIDE

摘要

The O-specific polysaccharide of the lipopolysaccharide produced by Hafnia alvei strain 1220 contained D-glucose, D-galactose, N-acetyl-D-glucosamine, N-acetyl-L-fucosamine (2-acetamido-2,6-dideoxy-L-galactose), glycerol, and phosphate. It was proved by composition and methylation analyses, Smith degradation, dephosphorylation, and one- and two-dimensional H-1 NMR spectroscopy to be a teichoic acid-like polymer with a branched hexasaccharide repeating unit of the following structure: [GRAPHICS] (C) 1996 Elsevier Science Ltd.
