Taxonomic group: bacteria / Proteobacteria (Phylum: Proteobacteria) Associated disease:infection due to Klebsiella [ICD11: XN620]
The structure was elucidated in this paper NCBI PubMed ID:815413 Journal NLM ID:0043535 Publisher: Elsevier Institutions: Centre de Recherche sur les Macromolécules Végétales, C.N.R.S., Université Grenoble I, B.P. 68, 38402 Saint-Martin d'Hères cedex France
Sugar analysis of the capsular antigen K19 from Klebsiella and of the carboxyl-reduced derivative confirmed its classification into the chemotype containing rhamnose, galactose, glucose, and glucuronic acid residues. Partial acid hydrolysis and phage depolymerization of K19 provided respectively a modified, linear form of the polysaccharide and oligosaccharides of the repeating unit, these were used for the structural elucidation of the original polymer. Methylation analysis, Smith degradation, and 1H- and 13C-n.m.r. spectroscopy of the polysaccharide and derivatives permitted formulation of the following structure for K19: (formula; see text).
