beta-Elimination of glucosyluronic residues during methylation of an acidic polysaccharide from Erwinia chrysanthemi CU 643.
Carbohydr Res. 2001 Jun 04; 332(3):317-23.CR

Abstract

The Erwinia chrysanthemi CU643 EPS has a linear hexasaccharide repeating unit in which a 4-linked uronic acid residue is present. The EPS was methylated by either the NaOH-Me2SO-MeI or Li-dimsyl procedure. MALDI-TOF MS analysis of the methylated products indicates that the beta-eliminative degradation occurs during the methylation, as characterized by serial fragments of the hexasaccharide repeating units. The degradation was clearly defined from the methylation of a glucosyluronic-containing pyruvated pentasaccharide.
