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.

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.

Neuronal uridine metabolism

Acta Neurologica Scandinavica, 1992
Uridine and other nucleic acids form part of RNA, DNA, coenzymes, second messengers, etc. Uridine uptake in nerve cells is an expression of neuronal RNA synthesis. More knowledge of uridine functions in neurones may give a better understanding of mechanisms underlying dementia, and they could be useful in treating brain tumors.

Brain uridine monophosphate: reduced incorporation of uridine during avoidance learning

Brain Research, 1974
Abstract Avoidance training produced no detectable changes in the radioactivity incorporated from [5-3H]uridine into total RNA of mouse brain, but decreased the radioactivity in brain uridine monophosphate. The chemical response was largest in the subcortical forebrain, and did not occur in yoked control mice.

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.
