Feedback onhibition of uridine kinase by cytidine triphosphate and uridine triphosphate

Biochimica et Biophysica Acta (BBA) - Specialized Section on Nucleic Acids and Related Subjects, 1964
Abstract Uridine kinase was found to be the rate-limiting step in the anabolism of uridine to its successive nucleotide derivatives. This enzymatic activity was susceptible to feedback inhibition by the pyrimidine nucleoside triphosphate end-products; effective inhibition was exerted by UTP and even more strikingly by CTP.

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.

Measurements of uridine diphosphate glucose and uridine diphosphate galactose — an appraisal

European Journal of Pediatrics, 1995
The recent disproof of a major deficiency of uridine diphosphate galactose in galactosemia should not lead investigators to assume either that enzymatic methods are unreliable for uridine sugar assays or that a defect in galactosylation in galactosemia has been excluded.

NMR Studies on the Self-Association of Uridine and Uridine Analogues

Chemistry - A European Journal, 1998
Association constants for the dimerization of acylated uridine and two analogues, 4-thiouridine and 6-oxadihy- drouridine, have been determined in chloroform solution. At 293 K, self-as- sociation constants K were found to decrease in the order uridine> 6- oxadihydrouridine> 4-thiouridine.
