CcVHPO1 - Vanadium-dependent haloperoxidases

This gene was retrieved from Chondrus Crispus (Thapa et al.,2020). This gene is analogous to the Asparagopsis taxiformis bromoperoxidase. They follow the same principle and mechanism as the A.Taxiformis enzymes.

It is an enzyme from the family of bromide peroxidases and catalyzes the following reaction: HBr + H₂O₂ → HOBr + H₂O

The enzyme uses Vanadium as a co-factor in the catalysis of the bromoform. The active site features a vanadium oxide center attached to the protein via one histidine side chain. The enzymes catalyze the oxidation of bromide by hydrogen peroxide. Bromonium cation (Br⁺) that is generated attacks hydrocarbons (represented as R). They are only specific to the bromide and are unable to oxidize chloride at all. R-H + Br^- + H₂O₂ -> R-Br + H₂O₂ + OH^-
