MetaCyc Reaction: 6.2.1.3

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 6.2.1.3

Enzymes and Genes:
acyl-CoA synthetase : FAA2 ( Saccharomyces cerevisiae )
long-chain-fatty-acid--CoA ligase 1 Inferred from experiment : ACSL1 ( Homo sapiens )
acyl-CoA synthetase Inferred from experiment : LACS9 ( Arabidopsis thaliana col )

In Pathway: linoleate biosynthesis I (plants) , linoleate biosynthesis II (animals)

Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

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.
