Bromide peroxidase (EC 1.11.1.18, bromoperoxidase, haloperoxidase (ambiguous), eosinophil peroxidase) is an enzyme with systematic name bromide:hydrogen-peroxide oxidoreductase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

RH + HBr + H2O2 RBr + 2 H2O

Bromo peroxidases of red and brown marine algae (Rhodophyta and Phaeophyta) contain vanadate (vanadium bromoperoxidase). Otherwise vanadium is unusual cofactor in biology.[6] By virtue of this family of enzymes, a variety of brominated natural products have been isolated from marine sources.

Related chloroperoxidase enzymes effect chlorination. In the nomenclature of haloperoxidase, bromoperoxidases classically are unable to oxidize chloride at all. For example, eosinophil peroxidase appears to prefer bromide over chloride, yet is not considered a bromoperoxidase because it is able to use chloride.

Muricidae (was Murex) spp. snails have a bromoperoxidase used to produce Tyrian purple dye. The enzyme is very specific to bromide and physically stable, but has not been characterized as to its active site metal. As of 2019, no specific gene has been assigned to such an enzyme in the snail genome.[7] Such an activity is probably provided by symbiotic Bacillus bacteria instead.[8] The identified enzyme belongs to the alpha/beta hydrolase superfamily; a structure for a similar bromoperoxidase is available as PDB: 3FOB​. It runs on a catalytic triad of Ser 99, Asp 229 and His 258 and does not require metal cofactors.[9]
