Abstract:
Stewartan is a capsular polysaccharide produced by Erwinia stewartii, the causative agent of Stewart's wilt of maize. The structure of stewartan is shown, by a combination of methylation analysis, Li/ethylenediamine degradation, 1D and 2D NMR spectroscopy, partial acid hydrolysis and isolation of oligosaccharides, Smith degradation, MALDI-TOFMS analysis and exoglycosidase digestion, to have the following repeating unit: [sequence: see text]
