Characterization of an acyl-CoA synthetase from Arabidopsis thaliana.

One of the major goals of modern plant biotechnology is to manipulate lipid metabolism in oilseed crops to produce new and improved edible and industrial vegetable oils. Lipids constitute the structural components of cellular membranes and act as sources of energy for the germinating seed and are therefore essential to plant cell function. Both de novo synthesis and modification of existing lip...

An enzymic cycling method for the determination of free fatty acids with acyl-CoA synthetase and acyl-CoA hydrolase.

A method for measuring free fatty acids by enzymic cycling is described. Free fatty acids are converted to acyl-CoAs by acyl-CoA synthetase, then the acyl-CoAs are hydrolyzed back to the free fatty acids by acyl-CoA hydrolase in a cyclic fashion. The amounts of AMP produced during this cyclic reaction are determined from the absorbance at 340 nm in the presence of AMP deaminase and glutamate de...

Arachidonoyl-CoA synthetase. Separation from nonspecific acyl-CoA synthetase and distribution in various cells and tissues.

Arachidonoyl-CoA synthetase was solubilized from a particulate fraction of calf brain and human platelets using 1% Nonidet P-40 and 10 mM EDTA. Arachidonoyl-CoA synthetase from both preparations was separated from nonspecific (long chain) acyl-CoA synthetase (EC 6.2.1.3) by chromatography on hydroxylapatite. To further substantiate that the two acyl-CoA synthetases are distinct proteins, we sol...

Phosphorylation and Acetylation of Acyl-CoA Synthetase- I.

Long chain acyl-CoA synthetase 1 (ACSL1) contributes 50 to 90% of total ACSL activity in liver, adipose tissue, and heart and appears to direct the use of long chain fatty acids for energy. Although the functional importance of ACSL1 is becoming clear, little is understood about its post-translational regulation. In order to investigate the post-translational modifications of ACSL1 under differ...

A sensitive spectrophotometric assay for peroxisomal acyl-CoA oxidase.

A simple spectrophotometric assay was developed for peroxisomal fatty acyl-CoA oxidase activity. The assay, based on the H2O2-dependent oxidation of leuco-dichlorofluorescein catalysed by exogenous peroxidase, is more sensitive than methods previously described. By using mouse liver samples, cofactor requirements were assessed and a linear relationship was demonstrated between dye oxidation and...
