Studies on the molecular genetics of bacterial LPS serve at least two main purposes: (i) to help develop an understanding of the biology, biochemistry and genetics of this bacterial surface macromolecule, and (ii) to provide a basis for both vaccine development and virulence experiments. Both of these goals have been the driving force in studies of Yersinia LPS carried out during the last decade. Here we will review the progress made in the molecular genetics and biochemistry of Yersinia LPS. A deep understanding has been achieved with respect to Y. enterocolitica serotype O:3, reaching as far as a detailed analysis of the gene clusters directing the biosynthesis of the outer core oligosaccharide and of the O-ag. The O-ag gene clusters of Y. enterocolitica serotype O:8 and Y. pseudotuberculosis serotypes O:2a and O:5a have also been cloned and partially characterized LPS biosynthesis of these Yersinia species includes examples of the two major variations recognized in the biosynthesis of this macromolecule: (i) homopolymeric or O-antigen polymerase-independent biosynthesis, and (ii) heteropolymeric or O-antigen polymerase-dependent biosynthesis.

Pappas RS, Sweetman BJ, Ray S, Hellerqvist CG "Monomer sequence determination of carbohydrates using fast-atom bombardment mass spectrometry of periodate-oxidized acetate ester derivatives" -
Carbohydrate Research 197 (1990) 1-14
A derivatization method, adapted from that of Angel et al. (ref. 10), for sequencing sugar residues in partially degraded poly- and oligo-saccharides using positive-ion f.a.b.-m.s. is described. Derivative selection provides sequence information by directing fragmentation exclusively to both sides of glycosidic oxygen atoms and, in the case of opened rings, between glycosidic carbon and ring oxygen atoms. Polysaccharides or oligosaccharides are subjected to sequential periodate oxidation, borodeuteride reduction, and acetylation. The derivatized polysaccharides are then subjected to partial degradation, acetylation, and high-performance liquid chromatography (h.p.l.c.) purification. F.a.b.-m.s. data obtained on model compounds, using 3-nitrobenzyl alcohol as matrix for f.a.b.-m.s., demonstrated direction of fragmentation to both sides of the glycosidic oxygen atom in unoxidized residues, and to both sides of the acetal oxygen atoms in oxidized residues. Oligosaccharide linkage and sequence may thus be determined by observing fragmentation from both the reducing and non-reducing ends of the molecule. Two Salmonella lipopolysaccharides, derivatized by this procedure, were partially hydrolyzed and then acetylated. Analysis of the h.p.l.c.-purified oligosaccharide derivatives by f.a.b.-m.s. demonstrated the applicability of the technique for sequencing nmol quantities of branched structures.

Abe F, Yamauchi T "Pregnane glycosides from the roots of Asclepias tuberosa" -
Chemical and Pharmaceutical Bulletin 48(7) (2000) 1017-1022
Sixteen glycosides of pregnanes, including ikemagenin, lineolon, and a new pregnane, 3β,8β,14β,15β,16α-pentahydroxy-5α-pregnan-20-one, termed pleurogenin, were isolated from the roots of Asclepias tuberosa. Among ikemagenin and lineolon glycosides, one (1) was a known glycoside, and eight (2-7, 10, 13) were glycosides with new combinations of ikemagenin or lineolon and known sugar sequences composed of D-cymarose, D-oleandrose, D-thevetose and D-glucose. The structures of four new glycosides of ikemagenin (8, 9, 11, 12) and three of pleurogenin (14-16) were determined. The new glycosides have sugar sequences ranging from tetraoside to heptaosides.
