Abstract:
The major oligosaccharide from the core region of the lipopolysaccharide from R. trifolii ANU843 was isolated and its structure determined. It is a trisaccharide consisting of two galacturonic acid residues and one 3-deoxy-D-manno-2-octulosonic acid (KDO) residue. The two galacturonic acid residues are terminally linked alpha to the C-4 and C-7 atoms of KDO. This structure was determined through use of 1H- and 13C-n.m.r. spectroscopy, f.a.b.-m.s., and g.l.c.-m.s. techniques. This oligosaccharide had not previously been reported to be present in the lipopolysaccharides from Gram-negative bacteria.
