additional information the enzyme shows phospholipid hydroperoxide glutathione peroxidase activity and thioredoxin peroxidase activity. Thioredoxin peroxidase activity is higher than phospholipid hydroperoxidase activity in terms of efficiency and substrate affinities. No activity with glutathione + H2O2 Solanum lycopersicum ?
