Roles for the methylation of phosphatidylethanolamine
Current Opinion in Lipidology, 1998The methylation of phosphatidylethanolamine is an auxiliary pathway for phosphatidylcholine biosynthesis in liver. Two forms of the enzyme, phosphatidylethanolamine N-methyltransferase, which catalyses this reaction, are located on the endoplasmic reticulum and mitochondria-associated membranes.

Labeling Membranes with Fluorescent Phosphatidylethanolamine
Cold Spring Harbor Protocols, 2011INTRODUCTIONThe phospholipid phosphatidylethanolamine (PE) can be conjugated via its head group to a number of fluorophores, including rhodamine, BODIPY (boron-dipyrromethene; 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene), and NBD (N-(7-nitrobenz-2-oxa-1,3-diazole-4-yl)).

Angiogenic Potency of Amadori‐Glycated Phosphatidylethanolamine
Annals of the New York Academy of Sciences, 2005Abstract: Glycation has been thought to participate in diabetic vascular diseases. However, there are no reports about the effects of lipid glycation on endothelial dysfunction. In this study, we have evaluated whether Amadori‐glycated phosphatidylethanolamine (Amadori‐PE), a lipid‐linked glycation compound, affected proliferation, migration, and tube

Liquid crystalline phases of hydrated phosphatidylethanolamine
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1969Abstract In order to investigate liquid crystalline phases of hydrated phosphatidylethanolamine by electron microscopy, a negative staining technique was used. Since the presence of the different phases is a function of lipid concentration and temperature, the phosphatidylethanolamine-water system was studied at different states of swelling at ...

Phosphatidylethanolamine – in a pinch
Trends in Cell Biology, 2000Cells actively modulate the lipid composition of the cytoplasmic and outer leaflets of their membranes. Plasma membranes, for example, contain the aminophospholipids phosphatidylethanolamine (PtdEtn) and phosphatidylserine (PtdSer) mainly in the cytoplasmic side of the bilayer.

Phosphatidylethanolamine biosynthesis in isolated hamster heart
Canadian Journal of Biochemistry, 1982The pathways leading to the formation of phosphatidylethanolamine in isolated hamster hearts were investigated. The contributions of the CDP-ethanolamine and the base exchange pathways were studied by perfusion with [3H]ethanolamine. The radioactivity of ethanolamine in the heart reached a maximum at 5 min of perfusion and remained constant throughout

13C-enriched phosphatidylethanolamines from Escherichia coli
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1975Escherichia coli have been grown using [1-13C]acetate and [2-13C]acetate as the sole carbon source. The 13C NMR spectra of the whole cells and spheroplasts can be readily obtained but give limited information. The 13C NMR spectra of t-e isolated 13C-enriched phosphatidylethanolamines are assigned and analysed to give the biosynthetic pathway for ...

Diacylglycerol-phosphatidylethanolamine exchange in Escherichia coli
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1989The conversion of [3H]- or [14C]diacylglycerol to labelled phosphatidylethanolamine by dialysed, particulate fraction of Escherichia coli was studied. The reaction occurred in the presence of hydroxylamine, under which conditions, the synthesis of [14C]phosphatidylethanolamine from CDP-diacylglycerol and [14C]serine did not occur.

Phosphatidylcholine homeostasis in phosphatidylethanolamine-depleted Tetrahymena
Archives of Biochemistry and Biophysics, 1986The relative contributions of the two pathways of phosphatidylcholine biosynthesis, phosphatidylethanolamine N-methyltransferase (EC 2.1.1.17) and diacylglycerol: CDP-choline cholinephosphotransferase (EC 2.7.8.1), are altered in the ciliate protozoan Tetrahymena thermophila whose phospholipid composition has been modified by culturing the organism in ...

Infrared spectra of phosphatidylethanolamine–cardiolipin binary system
Colloids and Surfaces B: Biointerfaces, 2008We report on the infrared spectra of binary di-palmitoyl-phosphatidyl-ethanolamine-cardiolipin (DPPE 1-x CLPx) monolayers and multilamellar vesicles as a function of CLP molar fraction x and temperature T. These data, which clearly show the presence of, at least, two kind of lipid domains with different thermodynamic stability and ordering of the lipid
