title: Catabolism of carotenoids: Involvement of peroxidase?
abstract: In primary leaves of barley allowed to senesce under natural conditions, carotenoids, like chlorophylls, disappear gradually. Commercial horse-radish peroxidase catalizes the oxidation of lutein to unknown colorless products. This reaction depends on the presence of 2,4 dichlorophenol. It is independent of peroxide but is nullified in the presence of catalase. Preparations of thylakoids from barley chloroplasts show an activity with features comparable to those of horse-radish peroxidase.
