IUBMB Comments
Bromoperoxidases of red and brown marine algae (Rhodophyta and Phaeophyta) contain vanadate. They catalyse the bromination of a range of organic molecules such as sesquiterpenes, forming stable C-Br bonds. Bromoperoxidases also oxidize iodides.

Brings about the bromination of a range of organic molecules, forming stable C-Br bonds. Can also act on iodide ions. The enzymes of this group contain vanadium (V) bound to the active centre. Since the actual halogenating agents are the respective hypohalous acids, vanadium-containing halide peroxidases lack substrate specificity and regioselectivity.
