Phosphorylation of uridine and cytidine by uridine–cytidine kinase

Journal of Biotechnology, 2014
Uridine 5'-monophosphate (5'-UMP) and cytidine 5'-monophosphate (5'-CMP) were biosynthesized by recombinant uridine-cytidine kinase (UCK) and acetate kinase (ACK). The ack and uck genes from Escherichia coli K12 and the uck1, uck2 and ack genes from Lactobacillus bulgaricus ATCC 11842 were cloned and inserted into the plasmid pET-28a.

Biochemistry of uridine in plasma

Clinica Chimica Acta, 2011
Uridine is a pyrimidine nucleoside that plays a crucial role in synthesis of RNA, glycogen, and biomembrane. In humans, uridine is present in plasma in considerably higher quantities than other purine and pyrimidine nucleosides, thus it may be utilized for endogenous pyrimidine synthesis.

Preparation of uridine diphosphogalactose and uridine diphosphate

Analytical Biochemistry, 1964
Abstract A procedure for the production of UDP-Gal and UDP on a preparative scale has been elaborated using a bacterial mutant which accumulates UDP-Gal in the presence of galactose. This method provides several possibilities for labeling these compounds with radioactive isotopes.

Effects of uridine on kindling

Epilepsy & Behavior, 2008
The anticonvulsant effect of the nucleoside uridine has been studied for several decades with controversial results. One of its attractive properties is that as a natural endogenous molecule, it lacks the serious side effects of common antiepileptic drugs used today. In the current study, we examined the potential antiepileptogenic effect of uridine in

Uridine Kinase: Altered Enzyme with Decreased Affinities for Uridine and CTP

Archives of Biochemistry and Biophysics, 1998
Uridine kinase is the rate-limiting enzyme in the salvage pathway for uridine or cytidine of mammalian cells. Alignment of the uridine kinase sequence with other nucleoside and nucleotide kinases supports a common ancestor for all of these. Three polypeptide segments for the ATP site and three polypeptide segments for the acceptor nucleoside site have ...

Uridine phosphorylase and uridine kinase activities of the Ehrlich ascites carcinoma

Canadian Journal of Biochemistry, 1969
Uridine phosphorylase and uridine kinase in cell-free extracts of the Ehrlich ascites carcinoma were assayed by a radioactive-tracer technique. Under the assay conditions uridine phosphorylase had an optimum pH of 8.0 and an apparent Km value for uridine of 2.5 × 10−3 M.
