Enzyme Commission Primary Name: long-chain-fatty-acid—CoA ligase

Enzyme Commission Synonyms: acyl-CoA synθse, fatty acid thiokinase (long chain), acyl-activating enzyme, palmitoyl-CoA synthase, lignoceroyl-CoA synthase, arachidonyl-CoA synθse, acyl coenzyme A synθse, acyl-CoA ligase, palmitoyl coenzyme A synθse, thiokinase, palmitoyl-CoA ligase, acyl-coenzyme A ligase, fatty acid CoA ligase, long-chain fatty acyl coenzyme A synθse, oleoyl-CoA synθse, stearoyl-CoA synθse, long chain fatty acyl-CoA synθse, long-chain acyl CoA synθse, fatty acid elongase, LCFA synθse, pristanoyl-CoA synθse, ACS3, long-chain acyl-CoA synθse I, long-chain acyl-CoA synθse II, fatty acyl-coenzyme A synθse, long-chain acyl-coenzyme A synθse, FAA1

Standard Gibbs Free Energy (ΔrG in kcal/mol): -12.711731 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Acts on a wide range of long-chain saturated and unsaturated fatty acids, but the enzymes from different tissues show some variation in specificity. The liver enzyme acts on acids from C6 to C20; that from brain shows high activity up to C24.
