| uridine diphosphate n-acetylgalactosamine | <chemical> A nucleoside diphosphate sugar which serves as a source of n-acetylgalactosamine for glycoproteins, sulfatides and cerebrosides. Chemical name: Uridine 5'-(trihydrogen diphosphate), P'-(2-(acetylamino)-2-deoxy-alpha-D-galactopyranosyl) ester (12 Dec 1998) |
|---|---|
| uridine diphosphate n-acetylglucosamine | <chemical> Serves as the biological precursor of insect chitin, of muramic acid in bacterial cell walls, and of sialic acids in mammalian glycoproteins. Chemical name: Uridine 5'-(trihydrogen diphosphate), P'-(2-(acetylamino)-2-deoxy-alpha-D-glucopyranosyl) ester (12 Dec 1998) |
| uridine diphosphate n-acetylmuramic acid | A nucleoside diphosphate sugar which is formed from udp-n-acetylglucosamine and phosphoenolpyruvate. It serves as the building block upon which peptidoglycan is formed. (12 Dec 1998) |
| uridine diphosphate xylose | <chemical> The decarboxylation product of udpglucuronic acid, which is used for formation of the xylosides of seryl hydroxyl groups in mucoprotein synthesis. Also forms plant xylans. Chemical name: Uridine 5'-(trihydrogen diphosphate), P'-alpha-D-xylopyranosyl ester (12 Dec 1998) |
| uridine diphosphogalactose | A pyrophosphate group links the 5'-position of uridine and the 1 position of d-galactose. (05 Mar 2000) |
| uridine diphosphoglucose | A pyrophosphate group links the 5'-position of uridine and the 1-position of d-glucose; an intermediate in glycogen biosynthesis. Synonym: UDPglucose. Acronym: UDPG (05 Mar 2000) |
| uridine diphosphoglucose 4-epimerase | <enzyme> A necessary enzyme in the metabolism of galactose. It reversibly catalyses the conversion of udpglucose to udpgalactose. NAD+ is an essential component for enzymatic activity. Chemical name: UDPglucose 4-epimerase Registry number: EC 5.1.3.2 (12 Dec 1998) |
| uridine diphosphoglucuronic acid | Uridine diphosphoglucose in which the 6 CH2OH of the glucose has been oxidised to COOH (has become a glucuronyl residue); participates in the formation of conjugates of bilirubin or drugs such as aspirin. Acronym: UDPGA (05 Mar 2000) |
| uridine diphosphoxylose | <biochemistry> Monosaccharide pentose that is found in xylans, very abundant components of hemicelluloses. (18 Nov 1997) |
| 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 triphosphatase | <enzyme> Rn in chemline for deoxyuridine triphosphatase: EC 3.6.1.23 Registry number: EC 3.6.1.- Synonym: utpase (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) |
| acetate kinase | <enzyme> An enzyme that catalyses reversibly the phosphorylation of acetate in the presence of a divalent cation and ATP with the formation of acetylphosphate and ADP. It is important in the glycolysis process. Chemical name: ATP:acetate phosphotransferase Registry number: EC 2.7.2.1 (12 Dec 1998) |
