EC 2.7.7.103

Accepted name: L-glutamine-phosphate cytidylyltransferase

Reaction: CTP + N5-phospho-L-glutamine = diphosphate + N5-(cytidine 5'-diphosphoramidyl)-L-glutamine

Systematic name: CTP:phosphoglutamine cytidylyltransferase

Comments: The enzyme, characterized from the bacterium Campylobacter jejuni, is involved in formation of a unique O-methyl phosphoramidate modification on specific sugar residues within the bacterium's capsular polysaccharides.
