Cytokine‐stimulated iNOS Expression Requires Long Chain Fatty Acyl CoA Synthetase (ACSL)

Structure and regulation of rat long-chain acyl-CoA synthetase.

Complementary DNAs encoding rat long-chain acyl-CoA synthetase have been isolated. The cDNAs were identified using synthetic oligonucleotide probes based on partial amino acid sequences of lysyl endopeptidase peptides of the purified enzyme. Rat long-chain acyl-CoA synthetase is predicted to contain 699 amino acid residues and to have a calculated molecular weight of 78,177. Significant sequenc...

Reversible inactivation by noradrenaline of long-chain fatty acyl-CoA synthetase in rat adipocytes.

Incubation of rat adipocytes with the same range of noradrenaline concentrations that stimulate lipolysis caused a rapid and stable decrease in the activity of fatty acyl-CoA synthetase. Corticotropin, glucagon and dibutyryl cyclic AMP also decreased the activity of the enzyme. The effect of noradrenaline was apparent over a wide range of concentrations for the three substrates of the enzyme. A...

FATP2 is a hepatic fatty acid transporter and peroxisomal very long-chain acyl-CoA synthetase.

Fatty acid transport protein (FATP)2, a member of the FATP family of fatty acid uptake mediators, has independently been identified as a hepatic peroxisomal very long-chain acyl-CoA synthetase (VLACS). Here we address whether FATP2 is 1) a peroxisomal enzyme, 2) a plasma membrane-associated long-chain fatty acid (LCFA) transporter, or 3) a multifunctional protein. We found that, in mouse livers...

Enhancement of E. coli acyl-CoA synthetase FadD activity on medium chain fatty acids

FadD catalyses the first step in E. coli beta-oxidation, the activation of free fatty acids into acyl-CoA thioesters. This activation makes fatty acids competent for catabolism and reduction into derivatives like alcohols and alkanes. Alcohols and alkanes derived from medium chain fatty acids (MCFAs, 6-12 carbons) are potential biofuels; however, FadD has low activity on MCFAs. Herein, we gener...
