Calcium-dependent generation of N-acylethanolamines and lysophosphatidic acids by glycerophosphodiesterase GDE7.
Rahman I.A., Tsuboi K., Hussain Z., Yamashita R., Okamoto Y., Uyama T., Yamazaki N., Tanaka T., Tokumura A., Ueda N.
N-Acylethanolamines form a class of lipid mediators and include an endocannabinoid arachidonoylethanolamide (anandamide), analgesic and anti-inflammatory palmitoylethanolamide, and appetite-suppressing oleoylethanolamide.

N-Acylethanolamines form a class of lipid mediators and include an endocannabinoid arachidonoylethanolamide (anandamide), analgesic and anti-inflammatory palmitoylethanolamide, and appetite-suppressing oleoylethanolamide. In animal tissues, N-acylethanolamines are synthesized from N-acylated ethanolamine phospholipids directly by N-acylphosphatidylethanolamine-hydrolyzing phospholipase D or through multi-step pathways via N-acylethanolamine lysophospholipids. We previously reported that glycerophosphodiesterase (GDE) 4, a member of the GDE family, has lysophospholipase D (lysoPLD) activity hydrolyzing N-acylethanolamine lysophospholipids to N-acylethanolamines. Recently, GDE7 was shown to have lysoPLD activity toward lysophosphatidylcholine to produce lysophosphatidic acid (LPA). Here, we examined the reactivity of GDE7 with N-acylethanolamine lysophospholipids as well as the requirement of divalent cations for its catalytic activity. When overexpressed in HEK293 cells, recombinant GDE7 proteins of human and mouse showed lysoPLD activity toward N-palmitoyl, N-oleoyl, and N-arachidonoyl-lysophosphatidylethanolamines and N-palmitoyl-lysoplasmenylethanolamine to generate their corresponding N-acylethanolamines and LPAs. However, GDE7 hardly hydrolyzed glycerophospho-N-palmitoylethanolamine. Overexpression of GDE7 in HEK293 cells increased endogenous levels of N-acylethanolamines and LPAs. Interestingly, GDE7 was stimulated by micromolar concentrations of Ca<sup>2+</sup> but not by millimolar concentrations of Mg<sup>2+</sup>, while GDE4 was stimulated by Mg<sup>2+</sup> but was insensitive to Ca<sup>2+</sup>. GDE7 was widely distributed in various tissues of humans and mice with the highest levels in their kidney tissues. These results suggested that GDE7 is a novel Ca<sup>2+</sup>-dependent lysoPLD, which is involved in the generation of both N-acylethanolamines and LPAs. << Less

Molecular characterization of a phospholipase D generating anandamide and its congeners.

Anandamide (N-arachidonoylethanolamine) is known to be an endogenous ligand of cannabinoid and vanilloid receptors. Its congeners (collectively referred to as N-acylethanolamines) also show a variety of biological activities. These compounds are principally formed from their corresponding N-acyl-phosphatidylethanolamines by a phosphodiesterase of the phospholipase D-type in animal tissues. We purified the enzyme from rat heart, and by the use of the sequences of its internal peptides cloned its complementary DNAs from mouse, rat, and human. The deduced amino acid sequences were composed of 393-396 residues, and showed that the enzyme has no homology with the known phospholipase D enzymes but is classified as a member of the zinc metallohydrolase family of the beta-lactamase fold. As was overexpressed in COS-7 cells, the recombinant enzyme generated anandamide and other N-acylethanolamines from their corresponding N-acyl-phosphatidylethanolamines at comparable rates. In contrast, the enzyme was inactive with phosphatidylcholine and phosphatidylethanolamine. Assays of the enzyme activity and the messenger RNA and protein levels revealed its wide distribution in murine organs with higher contents in the brain, kidney, and testis. These results confirm that a specific phospholipase D is responsible for the generation of N-acylethanolamines including anandamide, strongly suggesting the physiological importance of lipid molecules of this class. << Less
