- Abstract
The structure of lipid A from lipopolysaccharide of Phyllobacterium trifolii PETP02, a nitrogen-fixing symbiotic bacterium, was studied. It was found that the lipid A backbone was composed of two 2,3-diamino-2,3-dideoxy- d-glucose (Glc pN3N) residues connected by a β-(1 → 6) glycosidic linkage, substituted by galacturonic acid (Gal pA) at position C-1 and partly decorated by a phosphate residue at C-4′ of the non-reducing Glc pN3N. Both diaminosugars were symmetrically substituted by 3-hydroxy fatty acids (14:0(3-OH) and 16:0(3-OH)). Ester-linked secondary acyl residues [i.e. 19:0cyc and 28:0(27-OH) or 28:0(27-4:0(3-OMe))] were located in the distal part of lipid A. A high similarity between the lipid A of P. trifolii and Mesorhizobium was observed and discussed from the perspective of the genetic context of both genomes.
