Mm. Rahman et al., THE STRUCTURE OF THE CAPSULAR POLYSACCHARIDE FROM A SWARMING STRAIN OF PATHOGENIC PROTEUS-VULGARIS, Carbohydrate research, 301(3-4), 1997, pp. 213-220
The structure was determined for the capsular polysaccharide (CPS) iso
lated from a swarming strain of Proteus vulgaris, CP2-96, which was ob
tained from the spleen of an infected mouse. The CPS was extracted fro
m the cell pellet by hot water, precipitated with ethanol, and further
purified by gel-permeation chromatography. The structure was establis
hed by glycosyl composition and linkage analyses, and by NMR spectrosc
opy. The sequence of the glycosyl residues was determined by a NOESY e
xperiment. The CPS is composed of a tetrasaccharide repeating unit wit
h the following structure: [GRAPHICS] (C) 1997 Elsevier Science Ltd.
