The novel structure of the core oligosaccharide backbone of the lipopolysaccharide from the Plesiomonas shigelloides strain CNCTC 80/89 (serotype O13)

Abstract

The new structure of the core oligosaccharide of Plesiomonas shigelloides CNCTC 80/89 (serotype O13) lipopolysaccharide has been investigated by chemical methods, 1H and 13C NMR spectroscopy and matrix-assisted laser-desorption/ionization time of flight (MALDI-TOF). It was concluded that the core oligosaccharide of P. shigelloides CNCTC 80/89 is a nonasaccharide with the following structure: [Display omitted] The position of glycine was determined by MALDI-TOF MS/MS analyses.
