Notes

Dimethylaminoethylphosphonate (DMAEP) was incorporated into the phospholipids of the ciliate protozoan Tetrahymena thermophila at the expense of both phosphatidylethanolamine and phosphatidylcholine, but it had no effect on the levels of the 2-aminoethylphosphonolipid. The newly formed DMAEP-lipid accounted for almost 50% of the phospholipids of the organism. The DMAEP was incorporated into the phospholipids using both the ethanolaminephosphotransferase and cholinephosphotransferase pathways. The DMAEP-lipid was not methylated to the trimethyl derivative, confirming the lack of methylation of phosphonolipids by Tetrahymena.
