Haloperoxidase activities in Arctic macroalgae

Haloperoxidase activities were assayed in 21 species of Arctic green, red and brown macroalgae collected in the Kongsfjord at Ny-Aalesund (Svalbard). The enzymes were specific for bromide and/or iodide, but not for chloride. Highest bromoperoxidase activities were found in the brown seaweeds Luminur...

Description
Summary:Haloperoxidase activities were assayed in 21 species of Arctic green, red and brown macroalgae collected in the Kongsfjord at Ny-Aalesund (Svalbard). The enzymes were specific for bromide and/or iodide, but not for chloride. Highest bromoperoxidase activities were found in the brown seaweeds Luminuria saccharina and L. digitata, whereas highest iodoperoxidase activities were measured in the green species Acrosiphonia sonderi and Enteromorpha compressa. Optimum pH for bromination ranged between pH 4 and 7.
