11. This enzyme is also called "'uridine diphosphogalactose-mucopolysaccharide galactosyltransferase " '. 12. This enzyme is also called "'uridine diphosphoglucose-nuatigenin glucosyltransferase " '. 13. This enzyme is also called "'uridine diphosphoglucose-sarsasapogenin glucosyltransferase " '. 14. Fibroblasts with inactivated Lig3 gene can be propagated in the media supplemented with uridine and pyruvate. 15. In all other tRNAs, this position is normally occupied by a pyrimidine ( often uridine ). 16. After the uridine nucleotide base is synthesized, the other bases, cytosine and thymine are synthesized. 17. UMP can then be converted to Uridine -5-trisphosphate ( UTP ) by two kinases reaction. 18. Uridine triacetate is a drug approved by FDA to be used in the treatment of hereditary orotic aciduria.19. The other starter unit for tunicamycin is uridine , which is produced from uridiine triphosphate ( UTP ). 20. TunN is a nucleotide diphosphatase, and catalyzes the removal of pyrophosphate from UTP to form uridine monophosphate.
