Résumé
In 1961, when Bremer and Greenberg (1Bremer J. Greenberg D.M. Biochim. Biophys. Acta. 1961; 46: 205-216Crossref Scopus (357) Google Scholar) characterized the methylation reactions that convert phosphatidylethanolamine (PE) 4The abbreviations used are: PE, phosphatidylethanolamine; PC, phosphatidylcholine; PEMT, phosphatidylethanolamine N-methyltransferase; ER, endoplasmic reticulum; AdoMet, S-adenosylmethionine; CT, CTP:phosphocholine cytidylyltransferase; CD, choline-deficient; TG, triacyglycerol(s); VLDL, very low density lipoprotein; HDL, high density lipoprotein; AdoHcy, S-adenosylhomocysteine; Hcy, homocysteine. 4The abbreviations used are: PE, phosphatidylethanolamine; PC, phosphatidylcholine; PEMT, phosphatidylethanolamine N-methyltransferase; ER, endoplasmic reticulum; AdoMet, S-adenosylmethionine; CT, CTP:phosphocholine cytidylyltransferase; CD, choline-deficient; TG, triacyglycerol(s); VLDL, very low density lipoprotein; HDL, high density lipoprotein; AdoHcy, S-adenosylhomocysteine; Hcy, homocysteine. to phosphatidylcholine (PC), it is unlikely that they would have predicted the physiological impact of this biosynthetic conversion.
