| phosphatidylethanolamine cytidylyltransferase | <enzyme> A key enzyme in the biosynthesis of cephaline. It catalyses the reaction of phosphoethanolamine and CTP to form CDP-ethanolamine and pyrophosphate. (05 Mar 2000) |
|---|
| choline-phosphate cytidylyltransferase | <enzyme> An enzyme that catalyses the transfer of cytidylate (CMP) to choline phosphate to form CDPcholine. It is the rate-limiting enzyme in the choline pathway for the biosynthesis of phosphatidylcholine. Its activity is increased by glucocorticoids. Registry number: EC 2.7.7.15 (12 Dec 1998) |
|---|---|
| CTP-RNA cytidylyltransferase | <enzyme> Catalyses addition of cmp residue to 3'-ends of oligonucleotide primers Registry number: EC 2.7.7.- Synonym: terminal cytidylyltransferase (26 Jun 1999) |
| n-acylneuraminate cytidylyltransferase | <enzyme> An enzyme that forms cmp-acylneuraminic acids, which donate the n-acylneuraminic acid residues to the terminal sugar residue of a ganglioside or glycoprotein. Chemical name: CTP:N-acylneuraminate cytidylyltransferase Registry number: EC 2.7.7.43 (12 Dec 1998) |
| D-ribitol-5-phoshate cytidylyltransferase | <enzyme> Catalyses reversibly the reaction of ctp and ribitol-5-phosphate to yield cdpribitol and pyrophosphate Registry number: EC 2.7.7.40 Synonym: cdpribitol pyrophosphorylase (26 Jun 1999) |
| phosphatidylethanolamine | <biochemistry> A major structural phospholipid in mammalian systems. Tends to be more abundant than phosphatidylcholine in the internal membranes of the cell and is an abundant component of prokaryotic membranes. Ethanolamine is attached to phosphatidic acid by a phosphodiester linkage. Synthesis from diacyl glycerol and CDP-ethanolamine. The condensation product of a phosphatidic acid and ethanolamine; found in biomembranes. See: cephalin. (05 Mar 2000) |
| phosphatidylethanolamine-ceramide phosphoethanolamine transferase | <enzyme> Cdpethanolamine is not a donor; involved in sphingomyelin synthesis Registry number: EC 2.7.8.- Synonym: pe-cer-pet transferase (26 Jun 1999) |
