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.

Phosphatidylethanolamine and Lysophosphatidylethanolamine [PDF]

Journal of Pharmacy and Pharmacology, 1963
Abstract Phosphatidylethanolamine and Lysophosphatidylethanolamine belong to a group of phospholipids generally termed cephalins. The phospholipids are universally distributed among living organisms and are thought to be essential components of cell membranes.

The milk fat globule size governs a physiological switch for biofilm formation by Bacillus subtilis

Frontiers in Nutrition, 2022
Milk lipids are organized in the form of milk fat globules (MFG), ranging in size from 0. 1 to 15 μm. The MFG size is closely associated with the composition of fatty acids, polar lipids, sphingolipids, cholesterol and the content of the MFG membrane ...

ABCA4 is an N-retinylidene-phosphatidylethanolamine and phosphatidylethanolamine importer [PDF]

Nature Communications, 2012
ATP-binding cassette (ABC) transporters comprise a superfamily of proteins, which actively transport a variety of compounds across cell membranes. Mammalian and most eukaryotic ABC transporters function as exporters, flipping or extruding substrates from the cytoplasmic to the extracellular or lumen side of cell membranes.

Conditional targeting of phosphatidylserine decarboxylase to lipid droplets

Biology Open, 2021
Phosphatidylethanolamine is an abundant component of most cellular membranes whose physical and chemical properties modulate multiple aspects of organelle membrane dynamics. An evolutionarily ancient mechanism for producing phosphatidylethanolamine is to

Porin 1 Modulates Autophagy in Yeast

Cells, 2021
Autophagy is a cellular recycling program which efficiently reduces the cellular burden of ageing. Autophagy is characterised by nucleation of isolation membranes, which grow in size and further expand to form autophagosomes, engulfing cellular material ...

Genome Analysis of a Variant of Streptomyces coelicolor M145 with High Lipid Content and Poor Ability to Synthetize Antibiotics

Microorganisms, 2023
Streptomyces coelicolor M145 is a model strain extensively studied to elucidate the regulation of antibiotic biosynthesis in Streptomyces species. This strain abundantly produces the blue polyketide antibiotic, actinorhodin (ACT), and has a low lipid ...

Lipid bilayer composition influences small multidrug transporters [PDF]

, 2008
Background: Membrane proteins are influenced by their surrounding lipids. We investigate the effect of bilayer composition on the membrane transport activity of two members of the small multidrug resistance family; the Escherichia coli transporter, EmrE
