Abstract

Summary The core oligosaccharide of Rhodocyclus gelatinosus Dr2 was isolated and its chemical structure examined by methylation analysis. The anomeric configurations of the linkages were determined by 1H-and 13C-nuclear magnetic resonance spectroscopy. The core contained one residue of 3-deoxy- D-mannooctulosonic acid (Kdo), which was assumed to be ketosidically linked to C-6′ of the non-reducing glucosamine of lipid A. The Kdo unit was substituted at C-4 by an α-1′4-linked galactopyranosuronic acid disaccharide and at C-5 by D-glycero- D-manno-heptopyranose, the latter of which was partially substituted by phosphate at C-7.
