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 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...
متن کاملArachidonoyl-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...
متن کاملCloning and characterization of a hormonally regulated rat long chain acyl-CoA synthetase.
A previously unidentified gonadotropin-regulated long chain acyl-CoA synthetase (GR-LACS) was cloned and characterized as a 79-kDa cytoplasmic protein expressed in Leydig cells of the rat testis. GR-LACS shares sequence identity with two conserved regions of the LACS and luciferase families, including the ATP/AMP binding domain and the 25-aa fatty acyl-CoA synthetase signature motif, but displa...
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...
