| guanosine diphosphate fucose | <chemical> A nucleoside diphosphate sugar formed from GDPmannose, which provides fucose for lipopolysaccharides of bacterial cell walls, and for blood group substances and other glycoproteins. Chemical name: Guanosine 5'-(trihydrogen diphosphate), P'-(6-deoxy-beta-L-galactopyranosyl) ester (12 Dec 1998) |
|---|---|
| guanosine diphosphate mannose | <chemical> A nucleoside diphosphate sugar which can be converted to the deoxy sugar GDPfucose, which provides fucose for lipopolysaccharides of bacterial cell walls. Also acts as mannose donor for glycolipid synthesis. Chemical name: Guanosine 5'-(trihydrogen diphosphate), mono-alpha-D-mannopyranosyl ester (12 Dec 1998) |
| guanosine diphosphate sugars | Esters formed between the aldehydic carbon of sugars and the terminal phosphate of guanosine diphosphate. (12 Dec 1998) |
| phosphatidylinositol 4,5-diphosphate | <biochemistry> A phosphoinositide present in all eukaryotic cells, particularly in the plasma membrane. It is the major substrate for receptor-stimulated phosphoinositidase c, with the consequent formation of inositol 1,4,5-triphosphate and diacylglycerol, and probably also for receptor-stimulated inositol phospholipid 3-kinase. (12 Dec 1998) |
| poly adenosine diphosphate ribose | <chemical> A polynucleotide formed from NAD in the presence of NAD+ nucleosidase. Chemical name: Adenosine 5'-(trihydrogen diphosphate), P'-5-ester with D-ribose, homopolymer (12 Dec 1998) |
| cytidine 5'-diphosphate | <biochemistry> An ester, at the 5' position, between cytidine and diphosphoric acid. It is derived from cytidine 5'-triphosphate and is important in phosphatide biosynthesis. Acronym: CDP (21 Jun 2000) |
| cytidine diphosphate | <chemical> Cytidine 5'-(trihydrogen diphosphate). A cytosine nucleotide containing two phosphate groups esterified to the sugar moiety. Synonym: crpp; cytidine pyrophosphate. Chemical name: Cytidine 5'-(trihydrogen diphosphate) (12 Dec 1998) |
| cytidine diphosphate choline | <chemical> Donor of choline in biosynthesis of choline-containing phosphoglycerides. Pharmacological action: nootropic agents. Chemical name: Cytidine 5'-(trihydrogen diphosphate), P'-(2-(trimethylammonio)ethyl) ester, inner salt (12 Dec 1998) |
| cytidine diphosphate diglycerides | The ester of diacylglycerol with the terminal phosphate of cytidine diphosphate. It serves as an intermediate in the biosynthesis of phosphatidylethanolamine and phosphatidylserine in bacteria. (12 Dec 1998) |
| dehydrodolichyl diphosphate synthetase | <enzyme> Membrane-associated prenyl transferase from rat seminiferous tubules; dependent on t,t-farnesyl diphosphate, isopentenyldiphosphate and divalent cation; also from yeast saccharomyces carlsbergensis; looses its activity in the presence of 0.1% triton x-100 Registry number: EC 2.5.1.- Synonym: long chain polyprenyl diphosphate synthetase, dddp synthetase, dehydrodolichyl diphosphate synthase (26 Jun 1999) |
| deoxynucleoside diphosphate-oligonucleotide deoxynucleotidyl transferase | <chemical> Activated by mg++ Synonym: dndp-deoxynucleotidyl transferase, ddodt (26 Jun 1999) |
| dimethylallyl diphosphate-umbelliferone 6-dimethyltransferase | <enzyme> Catalyses the 6-prenylation of umbelliferone, forming demethylsuberosin Registry number: EC 2.5.1.- Synonym: ddud-transferase (26 Jun 1999) |
| dimethylallyl diphosphate umbelliferone 7-O-dimethyltransferase | <enzyme> Catalyses the 7-o-prenylation of umbelliferone, forming o-prenylumbelliferone Registry number: EC 2.5.1.- Synonym: ddu7-transferase (26 Jun 1999) |
| diphosphate | <chemistry> Two phosphate groups linked by esterification. Released in many of the synthetic steps involving nucleotide triphosphates (e.g. Protein and nucleic acid elongation). Rapid cleavage by enzymes that have high substrate affinity ensures that these reactions are essentially irreversible. (18 Nov 1997) |
| dolichol phosphate glucose-dolichol diphosphate oligosaccharide glucosyltransferase | <enzyme> Can also use dolichol-p-galactose as donor Registry number: EC 2.4.1.- Synonym: dolichol-p-glucose-dolichol-p-p-oligosaccharide glucosyltransferase, dolichol-pp-oligosaccharide glucosyltransferase (ii), dolichol-p-p-oligosaccharide glucosyltransferase (i), dol-p-p-oligosaccharide glycosyltransferase, dppo-glucosyltransferase, dolichyl-p-glucose-man(9)(glcnac)2-pp-dolichol glucosyltransferase (26 Jun 1999) |
