In enzymology, a 2,4-dichlorobenzoyl-CoA reductase () is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are 4-chlorobenzoyl-CoA, NADP<sup>+</sup>, and HCl, whereas its 3 products are 2,4-dichlorobenzoyl-CoA (the thioester of 2,4-dichlorobenzoic acid), NADPH, and H<sup>+</sup>.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 4-chlorobenzoyl-CoA:NADP+ oxidoreductase (halogenating). This enzyme participates in degradation of 2,4-dichlorobenzoate.
