The 3 substrates of this enzyme are ATP, carboxylic 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 the glycine conjugation of xenobiotics and butanoate metabolism.
