DOPA peroxidase activity in the chloragogen cells of the earthworm, Lumbricus terrestris L

DOPA peroxidase activity of the cytosol of chloragocytes in the earthworm was proved by biochemical and histochemical methods, respectively. Chloragocyte DOPA peroxidase do not hydroxylate tyrosine, but it may oxidize besides DOPA other phenolie compounds in the presence of hydrogen peroxide. Probable participation of this enzyme in the detoxication of phenolie compounds and in the formation of chloragosomes was discussed.
