Vanadium bromoperoxidase

Its primary function is to remove hydrogen peroxide which is produced during photosynthesis from in or around the cell.

[3] While the purpose of the bromoperoxidase is still unknown, the leading theories include that it’s a way of regulating hydrogen peroxide produced by photosynthesis and/or as a self-defense mechanism by producing hypobromous acid which prevents the growth of bacteria.

[4][5] The enzymes catalyse the oxidation of bromide (0.0067% of sea water) by hydrogen peroxide.

The resulting electrophilic bromonium cation (Br+) attacks hydrocarbons (symbolized as R-H in the following equation): The bromination acts on a variety of dissolved organic matter and increasingly bromination leads to the formation of bromoform.

[7] Partially in the polar regions, which has high blooms of microalgae in the spring, these compounds have the potential to enter the troposphere and lower stratosphere.
