Acetyl phosphatidylethanolamine was compared with phosphatidylethanolamine in the reconstitution of several biological membrane activities with the following results. 1. The proton pump reconstituted with the purple membrane of Halobacterium halobium and acetyl phosphatidylethano
In Vitro Assay to Measure Phosphatidylethanolamine Methyltransferase Activity.
Phosphatidylethanolamine methyltransferases are biosynthetic enzymes that catalyze the transfer of one or more methyl group(s) from S-adenosyl-L-methionine onto phosphatidylethanolamine, monomethyl-phosphatidylethanolamine, or dimethyl-phosphatidylethanolamine to give either mono
Mitochondrial phosphatidylethanolamine level modulates Cyt c oxidase activity to maintain respiration capacity in Arabidopsis thaliana rosette leaves.
Phosphatidylethanolamine is the predominant phospholipid of the mitochondrial inner membrane. In Arabidopsis, pect1-4 mutants exhibit reduced cellular phosphatidylethanolamine levels owing to reduced CTP:phosphorylethanolamine cytidylyltransferase (PECT; EC 2.7.7.14) activity. Co
The polymorphic phase behaviour of phosphatidylethanolamines of natural and synthetic origin. A 31P NMR study.
1. The polymorphic phase behaviour of aqueous dispersions of phosphatidylethanolamines isolated from human erythrocytes, hen egg yolk and Escherichia coli have been investigated employing 31P NMR techniques. All species exhibit well defined, reversible bilayer to hexagonal (H11)
Cloning and expression of a novel phosphatidylethanolamine N-methyltransferase. A specific biochemical and cytological marker for a unique membrane fraction in rat liver.
Phosphatidylethanolamine N-methyltransferase catalyzes the synthesis of phosphatidylcholine from phosphatidylethanolamine and is most active in liver. A cDNA for this enzyme from a rat liver cDNA library has been cloned, sequenced, and expressed in COS-1 cells, McArdle-RH7777 rat
-induced fusion of sulfatide-containing phosphatidylethanolamine small unilamellar vesicles
The fusogenic properties of sulfatide-containing 1,2-dioleoyl-3sn -phosphatidylethanolamine (DOPE) small unilamellar vesicles (SUVs) in the presence of CaCl 2 were studied by mixing membrane lipids based on an assay of fluorescence resonance energy transfer (FRET). Fusion of the
Serine Regulates Phosphatidylethanolamine Biosynthesis
The role of serine as a precursor and metabolic regulator for phosphatidylethanolamine biosynthesis in the hamster heart was investigated. Hearts were perfused with 60 p~ [l-SH]ethanolamine in the presence or absence of serine for up to 60 min. Ethanolamine uptake was attenuated
Phosphatidylethanolamine biomimetic coating increases mesenchymal stem cell osteoblastogenesis.
Previous observations (e.g., decreased bacterial adhesion) have shed the light on the auspicious possibility to use phosphatidylethanolamine as biomimetic coating for metal implants. Additionally, it was experimentally shown that phosphatidylethanolamine induces bone formation, h
Phosphatidylserine functions as the major precursor of phosphatidylethanolamine in cultured BHK-21 cells.
Pulse-chase experiments with [3H]serine provide evidence that significant amounts of phosphatidylserine turn over to form phosphatidylethanolamine in mammalian cells in tissue culture. Phospholipase C hydrolysis of [3H]phosphatidylethanolamine synthesized from [3H]serine by baby
Conversion of Phosphatidylethanolamine to Phosphatidylcholine in Rat Liver
The enzymatic activities for the synthesis of phosphatidylcholine from phosphatidylethanolamine and Sadenosyl-L-methionine have been solubilized from rat liver microsomes by ultrasonic disruption in the presence of 0.2% Triton X-100. Significant co-purification of the activities
