Reinvestigation of the structure of Brucella O-antigens [PDF]
Carbohydrate Research, 2013 O-Specific polysaccharides of Brucella contain two antigenic determinants, called A and M. Most of the strains express epitope A with a small amount of epitope M, whereas Brucella melitensis strain 16 M expresses longer polymer consisting mostly of M-type epitopes.

Lipophilic O-antigens in Rhodospirillum tenue [PDF]
Journal of Bacteriology, 1977 Lipopolysaccharides of eight wild-type strains of the phototrophic bacterium Rhodospirillum tenue have been analyzed. All of the lipopolysaccharides are highly lipophilic. The compositions of preparations obtained by the phenol-water or by the phenol-chloroform-petroleum ether procedure are very similar. The polysaccharide moiety, obtained by mild acid

Mechanism of O-antigen distribution in lipopolysaccharide [PDF]
Journal of Bacteriology, 1990 O-antigen units are nonuniformly distributed among lipid A-core molecules in lipopolysaccharide (LPS) from gram-negative bacteria, as revealed by polyacrylamide gel electrophoresis in sodium dodecyl sulfate; the actual distribution patterns are complex, multimodal, and strain specific.

Identification of the lipopolysaccharide O‐antigen biosynthesis priming enzyme and the O‐antigen ligase in Myxococcus xanthus: critical role of LPS O‐antigen in motility and development [PDF]
Molecular Microbiology, 2019 SummaryMyxococcus xanthus is a model bacterium to study social behavior. At the cellular level, the different social behaviors of M. xanthus involve extensive cell–cell contacts. Here, we used bioinformatics, genetics, heterologous expression and biochemical experiments to identify and characterize the key enzymes in M.
