In Vitro O-Antigen Ligase Assay
2013WaaL is a membrane enzyme that catalyzes the glycosidic bonding of a sugar at the proximal end of the undecaprenyl-diphosphate (Und-PP)-O-antigen with a terminal sugar of the lipid A-core oligosaccharide (OS). This is a critical step in lipopolysaccharide synthesis.

Twenty six new O (O51-O76) and 24 new H (H18-H41) antigens forPlesiomonas shigelloides serotyping scheme were defined. The O antigens 54 and 57 were closely related to those ofShigella boydii 2 and 9, respectively, in an a, b-a, c type of relationship.

Immunochemistry of Salmonella O-Antigens
International Archives of Allergy and Applied Immunology, 2009The binding specificities of antibodies directed against the Salmonella sero-group A-specific O-antigen 2 determinant were characterized by precipitation-inhibition and enzyme-linked immunosorbent assay inhibition tests. Two different antigen O-2-specific antisera were investigated: one conventional factor O-2-serum (elicited by whole heat-killed ...

The lipopolysaccharide (LPS) is the major constituent of the outer leaflet of the outer membrane of Gram-negative bacteria. Its lipid A moiety is embedded in the membrane and serves as an anchor for the rest of the LPS molecule. The outermost repetitive glycan region of the LPS is linked to the lipid A through a core oligosaccharide (OS), and is ...

Structure of the O-antigen of Yersinia pseudotuberculosis O:4a revised
Carbohydrate Research, 2009The O-specific polysaccharide was isolated by mild acid degradation of the lipopolysaccharide of Yersinia pseudotuberculosis O:4a and studied by NMR spectroscopy, including 2D ROESY and (1)H, (13)C HMBC experiments. The following structure of the pentasaccharide repeating unit of the polysaccharide was established, which differs from the structure ...

New O and H antigens of the international antigenic scheme forPlesiomonas shigelloides
Folia Microbiologica, 2000A revised update of the International antigenic scheme for Plesiomonas shigelloides is presented. Twenty-six new O (O77-O102) and 10 new H (H42-H50 and H1a1d) antigens have been described since 1994. The sources of antigens are mostly human clinical strains, isolates from warmblooded animals and a few environmental cultures.

O-Polysaccharides (O-antigens) were isolated from Escherichia coli O13, O129, and O135 and studied by chemical analyses along with 2D (1)H and (13)C NMR spectroscopy. They were found to possess a common -->2)-l-Rha-(alpha1-->2)-l-Rha-(alpha1-->3)-l-Rha-(alpha1-->3)-d-GlcNAc-(beta1--> backbone, which is a characteristic structural motif of the O ...

The O-antigen is an important component of the outer membrane of Gram-negative bacteria. It is a repeat unit polysaccharide and consists of a number of repeats of an oligosaccharide, the O-unit, which generally has between two and six sugar residues.
