Low-energy collision-activated dissociation electrospray ionization tandem mass spectrometric analysis of Sinorhizobial succinoglycan monomers

Non-enzymatic Self-acetylation of α-Cyclosophorotridecaoses Isolated from Ralstonia solanacearum: Mass Spectrometric Study

“…Furthermore, the acetyl moiety of linear octassacharides was not released even after a CE of 70 eV was applied. 22 These facts provide evidence that the acetyl linkages attached to cyclic glucans are less stable than those attached to linear glucans when subjected to ESI collision-activated dissociation (CAD).…”

Structural and Functional Properties, Biosynthesis, and Patenting Trends of Bacterial Succinoglycan: A Review

“…The name of this exopolysaccharide (EPS) has been initially coined as succinoglucan because succinic acid is a present as a main moiety in the biopolymer and succinic acid is primarily composed of several glucose residues. Later, the name is changed to succinoglycan as one galactose residue per seven glucose residues are also present in the structure along with some non-carbohydrate substituents, namely pyruvate, succinate and acetate [2,3]. So far yield of bacterial succinoglycan up to 13.7 g/l [4] has only been reported from soil inhabiting bacteria like Agrobacterium tumefaciens, Agrobacterium radiobacter, Agrobacterium rhizogenes [5], Rhizobium radiobacter [6], Sinorhizobium meliloti [7], Ensifer meliloti [8] and Pseudomonas sp.…”
