Chloride peroxidase

In enzymology, a chloride peroxidase is an enzyme that catalyzes the chemical reaction


 * 2 RH + 2 Cl- + H2O2 $$\rightleftharpoons$$ 2 RCl + 2 H2O

The 3 substrates of this enzyme are RH, Cl&minus;, and H2O2, whereas its two products are RCl and H2O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a peroxide as acceptor (peroxidases). The systematic name of this enzyme class is chloride:hydrogen-peroxide oxidoreductase. This enzyme is also called chloroperoxidase. It employs one cofactor, heme.
