Rate-limiting Description

"An analysis of the available data on the cytidine pathway for the synthesis of phosphatidylcholine and phosphatidylethanolamine, by the logic derived from the theoretical principles of metabolic regulation, shows that the first two reactions catalysed by choline (ethanolamine) kinase and phosphocholine (phosphoethanolamine) cytidylyltransferase are rate-limiting, whereas the phosphocholine (phosphoethanolamine) transferase step is near equilibrium in rat liver.." (603639)

"This flux change was used to test the possible regulatory roles of ethanolamine kinase and of phosphoethanolamine cytidylyltransferase, which are rate-limiting enzymes of the cytidine pathway for the synthesis of phosphatidylethanolamine ." (Infante (1977) Biochem)

"The activities of the rate-limiting enzymes in the de novo synthesis of PC and PE, CTP:phosphocholine cytidylyltransferase (CT), and CTP:phosphoethanolamine cytidylyltransferase (ET), respectively, were measured in the retinas excised at 5:00, 9:00, 13:00, and 17:00 h from rats adapted to a 24-h cycle with lights on from 7:00 to 19:00 h."
