Effects of pH on inactivation of maize phosphoenolpyruvate carboxylase

Maize leaf phosphoenolpyruvate carboxylase (PEPC) is inactivated by incubation at pH's above neutrality. Both the amount and the rapidity of inactivation increase as the pH rises. The presence of phosphoenolpyruvate (PEP), malate, glucose 6-phosphate and dithiothreitol in the incubation medium...
