Abstract

On the basis of sugar and methylation analysis, selective removal of 3,6-dideoxy-L-xylohexose (colitose, Col), 1H and 13C NMR spectroscopy, including 1D NOE, 2D COSY, and 2D H-detected 1H, 13C heteronuclear multiple-quantum coherence (HMQC), the following structure of the repeating unit of the O-specific polysaccharide of Salmonella enterica ssp. arizonae O50 (Arizona 9a,9b) was established: [sequence: see text] The O-antigen studied includes a trisaccharide fragment alpha-Co1p-(1-->2)-beta-D-Galp-(1-->3)-beta-D-GlcpNAc, which is a colitose ('3-deoxy-L-fucose') analogue of the Lewis (precursor) blood group antigen.
