Regulation of maize catalase by changing rates of synthesis and degradation

Abstract
Rates of catalase synthesis and degradation were measured in the scutellum of the germinating maize [Zea mays] seedling by the technique of Price, Sterling, Tarantola, Hartley et Rechcigl by using the porphyrinogenic drug 2-allyl-2-isopropylacetamide to inhibit catalase synthesis. Apparently developmental changes in catalase activity are determined by changes in the rate of enzyme degradation as well as by changes in the rates of its synthesis.
