Elucidation of the O-chain structure from the lipopolysaccharide of Agrobacterium tumefaciens strain C58

Elucidation of the O-chain structure from the lipopolysaccharide of Agrobacterium tumefaciens strain C58

A linear homopolysaccharide built of 3-α- l-6dTal p residues, randomly acetylated at position C-4, is described for the O-specific polysaccharide of Agrobacterium tumefaciens strain C58. This structure, determined by spectroscopical and chemical methods, is strictly correlated to that of Rhizobium l...

Zusammenfassung:A linear homopolysaccharide built of 3-α- l-6dTal p residues, randomly acetylated at position C-4, is described for the O-specific polysaccharide of Agrobacterium tumefaciens strain C58. This structure, determined by spectroscopical and chemical methods, is strictly correlated to that of Rhizobium loti strain NZP2213, which differs for the degree and the position of O-acetylation.
