AB Illumination (22,000 lumens per meter2) of etiolated maize plants for 80 hours brings about a 5-fold increase in phosphoenolpyruvate carboxylase activity per unit of protein. An increase in carboxylase protein and incorporation of [35S]methionine into the protein occurs simultaneously with the activity increase. In green plants, the level of phosphoenolpyruvate carboxylase protein and enzyme activity is dependent on the intensity of light during growth. These results are consistent with the conclusion that the activity increase results from light-stimulated de novo synthesis of phosphoenolypyruvate carboxylase protein.
