ATP + 3-hydroxybenzoate + CoA = AMP + diphosphate + 3-hydroxybenzoyl-CoA
3-hydroxybenzoyl-CoA synthetase; 3-hydroxybenzoate—coenzyme A ligase (AMP-forming); 3-hydroxybenzoyl coenzyme A synthetase; 3-hydroxybenzoyl-CoA ligase
3-hydroxybenzoate:CoA ligase (AMP-forming)
The enzyme works equally well with 4-hydroxybenzoate but shows low activity towards benzoate, 4-aminobenzoate, 3-aminobenzoate, 3-fluorobenzoate, 4-fluorobenzoate, 3-chlorobenzoate, and 4-chlorobenzoate. There is no activity with 3,4-dihydroxybenzoate, 2,3-dihydroxybenzoate, and 2-hydroxybenzoate as substrates.
