<i>Campylobacter jejuni</i> is a Gram-negative, pathogenic bacterium that causes campylobacteriosis, a form of gastroenteritis. <i>C. jejuni</i> is the most frequent cause of food-borne illness in the world, surpassing <i>Salmonella</i> and <i>E. coli</i>. Coating the surface of <i>C. jejuni</i> is a layer of sugar molecules known as the capsular polysaccharide that, in <i>C. jejuni</i> NCTC 11168, is composed of a repeating unit of d-glycero-l-gluco-heptose, d-glucuronic acid, d-<i>N</i>-acetyl-galactosamine, and d-ribose. The d-glucuronic acid moiety is further amidated with either serinol or ethanolamine. It is unknown how these modifications are synthesized and attached to the polysaccharide. Here, we report the catalytic activities of two previously uncharacterized, pyridoxal phosphate (PLP)-dependent enzymes, Cj1436 and Cj1437, from <i>C. jejuni</i> NCTC 11168. Using a combination of mass spectrometry and nuclear magnetic resonance, we determined that Cj1436 catalyzes the decarboxylation of l-serine phosphate to ethanolamine phosphate. Cj1437 was shown to catalyze the transamination of dihydroxyacetone phosphate to (<i>S</i>)-serinol phosphate in the presence of l-glutamate. The probable routes to the ultimate formation of the glucuronamide substructures in the capsular polysaccharides of <i>C. jejuni</i> are discussed. << Less
