Detailed structural characterization of succinoglycan, the major exopolysaccharide of Rhizobium meliloti Rm1021

Year: 1994

Type: article

Abstract: The detailed structure of the symbiotically important exopolysaccharide succinoglycan from Rhizobium meliloti Rm1021 was determined by mass spectrometry with electrospray ionization and collision-induced dissociation of the octameric oligosaccharide repeating unit. Previously undetermined locations of the succinyl and acetyl modifications were determined, in respect to both residue locations within the octamer and the carbon positions within the pyranose ring. Glycosidic linkages determined previously by methylation analysis were also verified.
