, whereas its 3 products are AMP, diphosphate, and benzoyl-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 benzoate:CoA ligase (AMP-forming). Other names in common use include benzoate-coenzyme A ligase, benzoyl-coenzyme A synthetase, and benzoyl CoA synthetase (AMP forming). This enzyme participates in benzoate degradation via coa ligation.
