 == Function ==
-'''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-containing, vanadium-containing or metal-free.  BPO from marine algae is vanadium-containing<ref>PMID:19363038</ref>.
