Phosphoenolpyruvate Carboxylase Activity In Norway Spruce Needles: Effects Of Air Pollutants Under Controlled Conditions

  • Hartwig Hohlfeld , Cornelius Lütz and Dieter Strack

The effect of mixtures of air pollutants (SO2, NO2, O3) on phosphoenolpyruvate carboxylase (PEPCase; EC 4.1.1.31) activities from needles of four-year-old Norway spruce (Picea abies [L.] Karst.) in closed fumigation chambers were analyzed. Three months exposure to high concentrations of O3 (1030 µg/m3) together with SO2 (1030 µg/m3) or NO2 (615 µg/m3) resulted in a dramatic increase in PEPCase activities
