Biosynthesis of CDP-α-d-fucofuranose and CDP-β-l-6-deoxy-altrofuranose for the Capsular Polysaccharides of .

is a Gram-negative human pathogen and is the most common cause of gastroenteritis in the United States and Europe. expresses a capsular polysaccharide (CPS) that enables the evasion of the host immune response and adherence to host epithelial cells. The various subspecies (serotypes) of are distinguished by their unique CPS repeating units.

Biosynthesis of UDP-β-l-Arabinofuranoside for the Capsular Polysaccharides of .

is the leading cause of food poisoning in North America and Europe. The exterior surface of this bacterium is coated with a capsular polysaccharide (CPS) which enables adherence to the host epithelial cells and evasion of the host immune system. Many strains of can be differentiated from one another by changes in the sequence of the carbohydrates found within the CPS.
