IUBMB Enzyme Nomenclature


Accepted name: glutamine kinase

Reaction: ATP + L-glutamine + H2O = AMP + phosphate + N5-phospho-L-glutamine

Systematic name: ATP:L-glutamine N5-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.
