  • Title: 3-Deoxy-octulosonic acid-containing trisaccharide fragment of an unusual core type of some Hafnia alvei lipopolysaccharides.
    Author: Katzenellenbogen E, Gamian A, Romanowska E, Dabrowski U, Dabrowski J.
    Journal: Biochem Biophys Res Commun; 1993 Aug 16; 194(3):1058-64. PubMed ID: 7688960.
    Abstract:
    The 3-deoxy-octulosonic acid-containing trisaccharide was isolated from the carbohydrate material obtained after the acid hydrolysis of lipopolysaccharides of Hafnia alvei strains 2 and 1211 using gel filtration. For purification the trisaccharide fraction was rechromatographed on a Bio-Gel P2 column. On the basis of sugar and methylation analyses and 1H NMR spectroscopy the trisaccharide was identified as 3-deoxy-7-O-(6-O-acetyl-alpha-D-galactopyranosyl)-4-O-(alpha-L-glycero-D - mannoheptopyranosyl)-D-manno-2-octulopyranosic acid. The occurrence of such bifurcate Kdo-containing structure has not been previously reported in Enterobacteriaceae.
