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...
متن کاملEnhancement 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...
متن کاملFATP2 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...
متن کاملReversible 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...
متن کاملPhytanic acid activation in rat liver peroxisomes is catalyzed by long-chain acyl-CoA synthetase.
In Refsum disease, disorders of peroxisome biogenesis, and rhizomelic chondrodysplasia punctata, pathological accumulation of phytanic acid results from impaired alpha-oxidation of this branched-chain fatty acid. Previous studies from this laboratory indicated that activation of phytanic acid to its CoA derivative precedes its alpha-oxidation in peroxisomes. It was reported that this reaction i...
