Vanadate-Dependent Peroxidases in Macroalgae: Function, Applications, and Environmental Impact

Vanadate(V)-dependent haloperoxidases VHPOs in marine macroalgae catalyze the 2e- oxidation, by H2O2, of bromide and iodide (X−) to X+ species such as HOX, X2 and X3 −. Several other substrates, including sulfides, are also oxidized. In the active center, H2VO4 − is covalently attached to the Nε of a histidine residue, an arrangement that has successfully been modeled with synthetic analogs of the active center. Vanadium acts as a Lewis acid, forming an intermediate peroxido/hydroperoxido complex.
