4-hydroxybenzoyl-CoA thioesterase

In enzymology, a 4-hydroxybenzoyl-CoA thioesterase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are 4-hydroxybenzoyl-CoA and H2O, whereas its two products are 4-hydroxybenzoate and CoA.
This enzyme belongs to the family of hydrolases, specifically those acting on thioester bonds. The systematic name of this enzyme class is 4-hydroxybenzoyl-CoA hydrolase. This enzyme participates in 2,4-dichlorobenzoate degradation.
