After its synthesis, a portion of PE moves back to the ER. Two mitochondrial proteins located in the intermembrane space, Ups1p and Ups2p, have been shown to regulate PE metabolism by controlling the export of PE. It remains to be determined where PS is decarboxylated in mitochondria and ...
Escherichia coli possesses only three major phospholipid species in its membranes, making it one of the simplest organisms to study with regard to phospholipid biosynthesis. This chapter reviews these pathways with the recognition that this module is diverse in bacteria. Phosphatidylethanolamine (PE) com...

T. brucei has also been used as valuable model eukaryote to study various biological processes, including phospholipid biosynthesis6,32. The lipid composition of T. brucei is similar to that of other eukaryotes, with PC (45–60%) and PE (10–20%) representing the major glycerophospho- lipid ...

Phosphatidylcholine Biosynthesis in Saccharomyces cerevisiae : Effects on Regulation of Phospholipid Synthesis and Respiratory Competence Phosphatidylcholine (PC) can be synthesized via two distinct pathways. One pathway involves three sequential methylations of phosphatidylethanolamine (PE) (Bremer et al. , 19...
Phosphatidylethanolamine and phosphatidylcholine biosynthesis by the Kennedy pathway occurs at different sites in Trypanosoma brucei Phosphatidylethanolamine (PE) and phosphatidylcholine (PC) are among the most abundant phospholipids in biological membranes. In many eukaryotes, the CDP-ethanolamine and CDP-choli...
PEBP1 plays a key modulatory part in several protein kinase signaling cascades. PKC phosphorylates PEBP1, resulting in the release of Raf-1 and activation of MEK and ERK. PEBP1 is expressed in many tissues and implicated in the regulation of such physiological processes as membrane biosynthesis,...
Furthermore, the cardiomyopathy Barth syndrome is caused by defective CL biosynthesis (19). Phosphatidylethanolamine (PE) is more abundant in mammalian mitochondria than in other organelles and contributes ∼30% of mitochondrial phospholipids. PE participates in contractile ring disassembly during ...
The abbreviations are: CK, choline kinase; CPT, CDP-choline: 1.2-diacylglycerol cholinephosphotransferase; PEMT, phosphatidylethanolamine N-methyltransferase; AT, Lyso-PC acyltransferase; PC, phosphatidylcholine; PE, phosphatidylethanolamine. An alternative pathway for PC biosynthesis, of quan...
