Reinvestigation of the structure of Brucella O-antigens [PDF]

open access: yesCarbohydrate 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.

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]

open access: yesMolecular 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.
