Metabolite Identification
Common NamePE(16:0/16:0)
DescriptionPE(16:0/16:0), also known as pe(16:0/16:0) or PE(32:0), belongs to the class of organic compounds known as phosphatidylethanolamines. These are glycerophosphoetahnolamines in which two fatty acids are bonded to the glycerol moiety through ester linkages. Thus, PE(16:0/16:0) is considered to be a glycerophosphoethanolamine lipid molecule. PE(16:0/16:0) is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. PE(16:0/16:0) exists in all living species, ranging from bacteria to humans. PE(16:0/16:0) participates in a number of enzymatic reactions, within cattle. In particular, Cytidine monophosphate and PE(16:0/16:0) can be biosynthesized from CDP-ethanolamine and DG(16:0/16:0/0:0); which is catalyzed by the enzyme choline/ethanolaminephosphotransferase. In addition, PE(16:0/16:0) can be biosynthesized from PS(16:0/16:0) through the action of the enzyme phosphatidylserine decarboxylase. In cattle, PE(16:0/16:0) is involved in the metabolic pathway called phosphatidylcholine biosynthesis PC(16:0/16:0) pathway.

Enzyme Details
1. Ethanolaminephosphotransferase 1
General function:
Involved in ethanolaminephosphotransferase activity
Specific function:
Catalyzes phosphatidylethanolamine biosynthesis from CDP-ethanolamine. It thereby plays a central role in the formation and maintenance of vesicular membranes. Involved in the foramtion of phosphatidylethanolamine via 'Kennedy' pathway (By similarity).
Gene Name:
SELENOI
Uniprot ID:

2. Phosphatidylethanolamine N-methyltransferase
General function:
Involved in phosphatidylethanolamine N-methyltransferas
Specific function:
Catalyzes the three sequential steps of the methylation pathway of phosphatidylcholine biosynthesis, the SAM-dependent methylation of phosphatidylethanolamine (PE) to phosphatidylmonomethylethanolamine (PMME), PMME to phosphatidyldimethylethanolamine (PDME), and PDME to phosphatidylcholine (PC).

Enzyme Details
3. Cytosolic phospholipase A2
General function:
Involved in calcium ion binding
Specific function:
Has primarily calcium-dependent phospholipase and lysophospholipase activities, with a major role in membrane lipid remodeling and biosynthesis of lipid mediators of the inflammatory response (By similarity). Plays an important role in embryo implantation and parturition through its ability to trigger prostanoid production (By similarity). Preferentially hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity). Selectively hydrolyzes sn-2 arachidonoyl group from membrane phospholipids, providing the precursor for eicosanoid biosynthesis via the cyclooxygenase pathway. In an alternative pathway of eicosanoid biosynthesis, hydrolyzes sn-2 fatty acyl chain of eicosanoid lysophopholipids to release free bioactive eicosanoids. Hydrolyzes the ester bond of the fatty acyl group attached at sn-1 position of phospholipids (phospholipase A1 activity) only if an ether linkage rather than an ester linkage is present at the sn-2 position. This hydrolysis is not stereospecific. Has calcium-independent phospholipase A2 and lysophospholipase activities in the presence of phosphoinositides. Has O-acyltransferase activity. Catalyzes the transfer of fatty acyl chains from phospholipids to a primary hydroxyl group of glycerol (sn-1 or sn-3), potentially contributing to monoacylglycerol synthesis (By similarity).
