'''Haloperoxidases''' catalyze the oxidation of halides by hydrogen peroxide while adding a halide to hydrocarbons. They are classified as '''chloroperoxldase''' (CPO), '''bromoperoxidase''' (BPO) and '''iodoperoxidase''' (IPO) according to the halide which they oxidize. CPO is heme-, vanadium-containing or metal-free. BPO from marine algae is vanadium-containing.
