Biological Properties
General Function Involved in ATP binding
Specific Function Phosphorylates uridine and cytidine to uridine monophosphate and cytidine monophosphate. Does not phosphorylate deoxyribonucleosides or purine ribonucleosides. Can use ATP or GTP as a phosphate donor. Can also phosphorylate cytidine and uridine nucleoside analogs such as 6-azauridine, 5-fluorouridine, 4-thiouridine, 5-bromouridine, N(4)-acetylcytidine, N(4)-benzoylcytidine, 5-fluorocytidine, 2-thiocytidine, 5-methylcytidine, and N(4)-anisoylcytidine.
Pathways
  • CTP biosynthesis via salvage pathway
  • Drug metabolism - other enzymes
  • Pyrimidine metabolism
  • UMP biosynthesis via salvage pathway
