In enzymology, a butyrate-CoA ligase, also known as XM-ligase, (EC 6.2.1.2) is an enzyme that catalyzes the chemical reaction
- ATP + an acid + CoA AMP + diphosphate + an acyl-CoA
The 3 substrates of this enzyme are ATP, acid, and CoA, whereas its 3 products are AMP, diphosphate, and acyl-CoA.
This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bonds as acid-thiol ligases. This enzyme participates in butanoate metabolism.
Nomenclature
The systematic name of this enzyme class is butanoate:CoA ligase (AMP-forming). Other names in common use include:
- butyryl-CoA synthetase, fatty acid thiokinase (medium chain),
- acyl-activating enzyme, fatty acid elongate,
- fatty acid activating enzyme,
- fatty acyl coenzyme A synthetase,
- medium chain acyl-CoA synthetase,
- butyryl-coenzyme A synthetase,
- L-(+)-3-hydroxybutyryl CoA ligase,
- xenobiotic/medium-chain fatty acid ligase, and
- short-chain acyl-CoA synthetase.
