[Chemico-enzymatic synthesis of Salmonella newington O-specific polysaccharide and its modified derivatives].
Treatment of the DMan (beta 1-4) LRha (alpha 1-3) D [3H]Gal-derivative of moraprenyl pyrophosphate with the cell envelope preparation from S. newington results in the formation of polysaccharide with beta 1-6 linkage between the trisaccharide units (polymerization degree approximately 8). The synthetic derivatives of moraprenyl pyrophosphate which contain D-talose, 4-deoxy-D-xylo-hexose, LRha (alpha 1-3) DGlc or LRha (alpha 1-3) DGlc (alpha 1-6) DGal were found to serve as substrates for the biosynthesis of the corresponding modified polysaccharides.
