In enzymology, a biotin—CoA ligase (EC 6.2.1.11) is an enzyme that catalyzes the chemical reaction
- ATP + biotin + CoA AMP + diphosphate + biotinyl-CoA
The 3 substrates of this enzyme are ATP, biotin, and CoA, whereas its 3 products are AMP, diphosphate, and biotinyl-CoA.
This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bonds as acid-thiol ligases. The systematic name of this enzyme class is biotin:CoA ligase (AMP-forming). Other names in common use include biotinyl-CoA synthetase, biotin CoA synthetase, and biotinyl coenzyme A synthetase. This enzyme participates in biotin metabolism.
