摘要
The rough-type lipopolysaccharide (LPS) of the plague pathogen, Yersinia pestis, was studied after mild-acid and. strong-alkaline degradations by chemical analyses, NMR spectroscopy and electrospray-ionization mass spectrometry, and the following structure of the core region was determined: [GRAPHICS] where L-alpha-D-Hep stands for L-glycero-alpha-D-manno-heptose, Sug1 for either 3-deoxy-alpha-D-manno-oct-2-ulosonic acid (alpha-Kdo) or D-glycero-alpha-D-talo-oct-2-ulosonic acid (alpha-Ko), and Sug2 for either beta-D-galactose or D-glycero-alpha-D-manno-heptose. A minority of the LPS molecules lacks GlcNAc. (C) 2002 Elsevier Science Ltd. All rights reserved.
