| 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) |
| phosphatidylcholine-ceramide phosphocholine transferase | <enzyme> Cdpcholine is not a donor; imvolved in sphingomyelin synthesis Registry number: EC 2.7.8.- Synonym: pc-cer-pch transferase, sphingomyelin synthase (26 Jun 1999) |
| 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) |
| phosphocholine | (CH3)3N+-CH2 CH2-OPO3 H-; choline O-phosphate;important in choline metabolism, e.g., as in cytidinediphosphocholine and in the biosynthesis of lecithins. Synonym: O-phosphocholine, phosphorylcholine. Phosphocholine cytidylyltransferase, an enzyme that catalyses the reaction of phosphocholine with CTP to form pyrophosphate and CDP-choline; the rate-limiting step of lecithin biosynthesis; the cytosolic form of the enzyme is inactive (a phosphorylated form of the enzyme). Phosphocholine diacylglycerol transferase, an enzyme in lecithin biosynthesis that catalyses the reaction of 1,2-diacylglycerol with CDP-choline to form CMP and phosphatidylcholine. (05 Mar 2000) |

| 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) |
