Campylobacter jejuni is a pathogenic Gram-negative bacterium and a leading cause of food-borne gastroenteritis. C. jejuni produces a capsular polysaccharide (CPS) that contains a unique O-methyl phosphoramidate modification (MeOPN). Recently, the first step in the biosynthetic pathway for the assembly of the MeOPN modification to the CPS was elucidated. It was shown that the enzyme Cj1418 catalyzes the phosphorylation of the amide nitrogen of l-glutamine to form l-glutamine phosphate. In this investigation, the metabolic fate of l-glutamine phosphate was determined. The enzyme Cj1416 catalyzes the displacement of pyrophosphate from MgCTP by l-glutamine phosphate to form CDP-l-glutamine. The enzyme Cj1417 subsequently catalyzes the hydrolysis of CDP-l-glutamine to generate cytidine diphosphoramidate and l-glutamate. The structures of the two novel intermediates, CDP-l-glutamine and cytidine diphosphoramidate, were confirmed by <sup>31</sup>P nuclear magnetic resonance spectroscopy and mass spectrometry. It is proposed that the enzyme Cj1416 be named CTP:phosphoglutamine cytidylyltransferase and that the enzyme Cj1417 be named γ-glutamyl-CDP-amidate hydrolase. << Less
