IUBMB Enzyme Nomenclature


Accepted name: cytidine diphosphoramidate kinase

Reaction: ATP + cytidine 5'-diphosphoramidate = ADP + cytidine 3'-phospho-5'-diphosphoramidate

Systematic name: ATP:cytidine 5'-diphosphoramidate 3'-phosphotransferase

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.
