Structure and Function of Carnitine Acyltransferases [PDF]

Annals of the New York Academy of Sciences, 2004
Abstract: Carnitine acyltransferases catalyze the exchange of acyl groups between carnitine and coenzyme A (CoA). These enzymes include carnitine acetyltransferase (CrAT), carnitine octanoyltransferase (CrOT), and carnitine palmitoyltransferases (CPTs).

Mitochondrial acyltransferases and glycerophospholipid metabolism

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2017
Our understanding of the synthesis and remodeling of mitochondrial phospholipids remains incomplete. Two isoforms of glycerol-3-phosphate acyltransferase (GPAT1 and 2) and two isoforms of acylglycerol-3-phosphate acyltransferase (AGPAT4 and 5) are located on the outer mitochondrial membrane, suggesting that both lysophosphatidic acid and phosphatidic ...

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.

[7] Coenzyme a-independent acyltransferase

1992
Publisher Summary This chapter describes coenzyme A-independent acyltransferase. The coenzyme A (CoA)-independent transacylation system catalyzes the transfer of fatty acids from diradyl phospholipids to various lysophospholipids in the absence of any cofactors, differing from the CoA-dependent transacylation reaction, which requires the presence of ...

[10] Dihydroxyacetone phosphate acyltransferase

1992
Publisher Summary Dihydroxyacetone phosphate acyltransferase (DHAPAT) catalyzes the transfer of the fatty acid moiety from long-chain acyl-coenzyme A (acyl-CoA) to the free hydroxyl group of dihydroxyacetone phosphate. This reaction initiates the synthesis of the ether-linked glycerolipids and the more common glycerol ester lipids.

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 ...

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 ...

[11] Diacylglycerol acyltransferase and monoacylglycerol acyltransferase from liver and intestine

1992
Publisher Summary The acylation of diacylglycerol catalyzed by the diacylglycerol acyltransferase is the only enzyme reaction unique to triacylglycerol synthesis. This reaction lies at the diacylglycerol branch point of phosphatidylcholine, phosphatidylethanolamine, and triacylglycerol synthesis.
