| UDP | uridine diphosphate |
|---|---|
| UDPG | uridine diphosphate glucose; urine diphosphoglucose |
| UDPGA | uridine diphosphate glucuronic acid |
| UDPGT | uridine diphosphate glucuronosyl transferase |
| UGT | uridine diphosphate-glucuronosyltransferase; urogenital tract; urogenital tuberculosis |
| uridine kinase | <enzyme> An enzyme that catalyses the phosphorylation of uridine and cytidine to uridine 5'-phosphate and cytidine 5'-phosphate, respectively. ATP, dutp, dGTP, and datp are effective phosphate donors. Chemical name: ATP:uridine 5'-phosphotransferase Registry number: EC 2.7.1.48 (12 Dec 1998) |
|---|---|
| uridine monophosphate | <chemical> 5'-uridylic acid. A uracil nucleotide containing one phosphate group esterified to the sugar moiety in the 2', 3' or 5' position. Chemical name: 5'-Uridylic acid (12 Dec 1998) |
| uridine monophosphate kinase | <enzyme> Catalyses the phosphorylation of ump to udp; an aspect of EC 2.7.4.4 Registry number: EC 2.7.4.- Synonym: ump kinase, uridine-5-monophosphate kinase, uridylate kinase (26 Jun 1999) |
| uridine nucleosidase | <chemical> Chemical name: nucleosidase, uridine Synonym: uridine ribohydrolase (26 Jun 1999) |
| uridine phosphorylase | <enzyme> An enzyme that catalyses the transfer of ribose from uridine to orthophosphate, forming uracil and ribose 1-phosphate. Chemical name: Uridine:orthophosphate alpha-D-ribosyltransferase Registry number: EC 2.4.2.3 (12 Dec 1998) |
| uridine-specific acid nuclease | <enzyme> Chicken liver enzyme hydrolyzes poly(u) and e. Coli RNA Registry number: EC 3.1.- (26 Jun 1999) |
| uridine triphosphate | A molecule which consists of the nitrogenous base uracil linked to the sugar ribose and which has a chain of three phosphate groups attached to the ribose in a linear fashion. UTP is required during transcription since it is a direct precursor of RNA. (09 Oct 1997) |
