Phosphatidylethanolamine Levels and Regulation of Phosphatidylethanolamine N- Methyltransferase

Journal of Biological Chemistry, 1989
The activity of phosphatidylethanolamine (PE) N-methyltransferase in liver microsomes, measured using endogenous microsomal PE as a substrate, was elevated 2-fold in the choline-deficient state. However, methyltransferase activity assayed in the presence of a saturating concentration of phosphatidyl-N-mono-methylethanolamine or microsomal PE was ...

Membrane phospholipid redistribution in cancer micro-particles and implications in the recruitment of cationic protein factors

Journal of Extracellular Vesicles, 2014
Cancer cell-derived micro-particles (MPs) play important regulatory roles on cellular and system levels. These activities are attributed in part to protein factors carried by MPs.

Serum phospholipids during aging: A comprehensive systematic review of cross-sectional and case-control studies [PDF]

Health Promotion Perspectives
Background: The lipidome, as a subset of metabolomics, can undergo significant variations due to several factors, including the aging process. Therefore, this study aims to summarize the relationship between aging and alterations in plasma phospholipids.

ExoS/ChvI Two-Component Signal-Transduction System Activated in the Absence of Bacterial Phosphatidylcholine

Frontiers in Plant Science, 2021
Sinorhizobium meliloti contains the negatively charged phosphatidylglycerol and cardiolipin as well as the zwitterionic phosphatidylethanolamine (PE) and phosphatidylcholine (PC) as major membrane phospholipids.

A rapid phospholipase D assay using zirconium precipitation of anionic substrate phospholipids: application to N-acylethanolamine formation in vitro

Journal of Lipid Research, 2000
Activation of phospholipase D (PLD) is involved in a number of signal transduction pathways in eukaryotic cells. The most common method for determination of PLD activity in vitro involves incubation with a radiolabeled substrate and lipid extraction ...

Enzymatic synthesis and decarboxylation of phosphatidylserine in Tetrahymena pyriformis

Journal of Lipid Research, 1970
Cell-free extracts of the protozoan Tetrahymena pyriformis have been found to catalyze the following reactions: Phosphatidylethanolamine+L-Serine⇌Phosphatidylserine+EthanolaminePhosphatidylserine→Phosphatidylethanolamine+CO2Net:L-Serine→Ethanolamine ...

Positional specificity of lysosomal phospholipase A2

Journal of Lipid Research, 2006
Lysosomal phospholipase A2 (Lpla2) is highly expressed in alveolar macrophages and may mediate the phospholipid metabolism of surfactant. Studies on the properties of this phospholipase are consistent with the presence of both phospholipase A1 and ...

PS, It’s Complicated: The Roles of Phosphatidylserine and Phosphatidylethanolamine in the Pathogenesis of Candida albicans and Other Microbial Pathogens

Journal of Fungi, 2018
The phospholipids phosphatidylserine (PS) and phosphatidylethanolamine (PE) play important roles in the virulence of Candida albicans and loss of PS synthesis or synthesis of PE from PS (PS decarboxylase) severely compromises virulence in C.

Identification and characterization of human ethanolaminephosphotransferase1

Journal of Lipid Research, 2007
CDP-ethanolamine:diacylglycerol ethanolaminephosphotransferase (EPT) catalyzes the transfer of phosphoethanolamine from CDP-ethanolamine to diacylglycerol to produce phosphatidylethanolamine (PE).

Phosphatidylethanolamine positively regulates autophagy and longevity [PDF]

Cell Death & Differentiation, 2015
Autophagy is a cellular recycling program that retards ageing by efficiently eliminating damaged and potentially harmful organelles and intracellular protein aggregates. Here, we show that the abundance of phosphatidylethanolamine (PE) positively regulates autophagy.
