| phosphatidate | A salt or ester of a phosphatidic acid. Phosphatidate phosphatase, an enzyme that catalyses the hydrolysis of phosphatidate producing inorganic phosphate and 1,2-diacylglycerol; this enzyme participates in phospholipid and triacylglycerol metabolism. (05 Mar 2000) |
|---|---|
| phosphatidate phosphatase | <enzyme> A phosphomonoesterase involved in the synthesis of triacylglycerols. It catalyses the hydrolysis of phosphatidates with the formation of diacylglycerols and orthophosphate. Chemical name: 3-sn-Phosphatidate phosphohydrolase Registry number: EC 3.1.3.4 (12 Dec 1998) |
| 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) |
| 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) |
| 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) |
