Structures of the O-antigens of Escherichia coli O13, O129, and O135 related to the O-antigens of Shigella flexneri

Carbohydrate Research, 2010
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 ...

Biosynthesis of O-antigens: genes and pathways involved in nucleotide sugar precursor synthesis and O-antigen assembly

Carbohydrate Research, 2003
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.
