Phospholipases and acyltransferases in macrophages

Klinische Wochenschrift, 1989
In contrast to many other cells, macrophages contain a phospholipase A2, which preferentially liberates arachidonic acid from the main phospholipids. In unstimulated macrophages this acylchain-specific phospholipase A2 is localized in the lipid-free cytosol and thus without function.

Physiological Functions of Phospholipid:Diacylglycerol Acyltransferases

Plant And Cell Physiology, 2023
Abstract Triacylglycerol (TAG) is among the most energy dense storage forms of reduced carbon in living systems. TAG metabolism plays critical roles in cellular energy balance, lipid homeostasis, cell growth and stress responses. In higher plants, microalgae and fungi, TAG is assembled by acyl-CoA-dependent and acyl-CoA-independent ...

ACYL-COENZYME A:CHOLESTEROL ACYLTRANSFERASE

Annual Review of Biochemistry, 1997
Due to its presumed role in regulating cellular cholesterol homeostasis, and in various pathophysiological conditions, acyl-coenzyme A:cholesterol acyltransferase (ACAT) has attracted much attention. Cloning the ACAT gene provides the necessary tool to advance molecular studies of this enzyme.

Lecithin cholesterol acyltransferase

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2000
Cholesterol transport in circulation and its removal from tissues depends on the activity of lecithin cholesterol acyltransferase (LCAT). LCAT is a soluble enzyme that converts cholesterol and phosphatidylcholines (lecithins) to cholesteryl esters and lyso-phosphatidylcholines on the surface of high-density lipoproteins.

Inhibitors of Acyl CoA:Cholesterol Acyltransferase

Journal of Medicinal Chemistry, 1996
Conformational restriction of previously disclosed acyclic (diphenylethyl)diphenylacetamides led to the discovery of several potent inhibitors of acyl CoA:cholesterol acyltransferase (ACAT). cis-[2-(4-Hydroxyphenyl)-1-indanyl]diphenylacetamide (4a) was the most potent ACAT inhibitor identified (IC50 = 0.04 microM in an in vitro rat hepatic microsomal ...

A review on lecithin:cholesterol acyltransferase deficiency

Clinical Biochemistry, 2015
Lecithin cholesterol acyl transferase (LCAT) is a plasma enzyme which esterifies cholesterol, and plays a key role in the metabolism of high-density lipoprotein cholesterol (HDL-C). Genetic disorders of LCAT are associated with lipoprotein abnormalities including low levels of HDL-C and presence of lipoprotein X, and clinical features mainly corneal ...

Serine carboxypeptidase-like acyltransferases

Phytochemistry, 2004
In plant secondary metabolism, an alternative pathway of ester formation is facilitated by acyltransferases accepting 1-O-beta-acetal esters (1-O-beta-glucose esters) as acyl donors instead of coenzyme A thioesters. Molecular data indicate homology of these transferases with hydrolases of the serine carboxypeptidase type defining them as serine ...

Purification and Characterization of Lecithin:Cholesterol Acyltransferase

Scandinavian Journal of Clinical and Laboratory Investigation, 1978
The purification of lecithin:cholesterol acyltransferase (LCAT] from human plasma is reported. Hydroxylapatite fractions were approximately 16,000 fold purified over the starting plasma and were free of high-density lipoprotein (HDL) and albumin.
