Biosynthesis of uridine
WebOral uridine, as described earlier, can be used where de novo biosynthesis of pyrimidines is defective, and it may be useful in reversing some effects of mitochondrial dysfunction and to minimize the toxic effect of the antitumor drug 5-fluorouracil. Uridine is also a precursor for UDP-glucose, essential for the deposition of glycogen in the liver. WebThe Uck2 gene, located on chromosome 1q22-23.2, encodes uridine-cytidine kinase 2 (Uck2), which is involved in the salvage pathway of pyrimidine-nucleotide biosynthesis. 4 Uck2 generally catalyzes the conversion of uridine and cytidine to the monophosphate form using adenosine triphosphate (ATP) as the phosphate donor. 5,6 Many studies have ...

Uridine (symbol U or Urd) is a glycosylated pyrimidine analog containing uracil attached to a ribose ring (or more specifically, a ribofuranose) via a β-N1-glycosidic bond. The analog is one of the five standard nucleosides which make up nucleic acids, the others being adenosine, thymidine, cytidine and guanosine. … See more Uridine is widely produced in nature as uridine monophosphate (uridylate) by de novo synthesis by the decarboxylation of orotidylate, which is catalyzed by orotidylate decarboxylase.
