ATP-Dependent Uptake of Malate in Vacuoles from CAM Plant, Kalanchoe Daigremontiana
Intracellular translocation of malate during crassulacean acid metabolism (CAM) is a complex phenomenon. The key enzyme phosphoenolpyruvate carboxylase catalyzes the synthesis of malate in cytoplasm has been established (Kluge and Tin, 1978). In the dark period the malate synthesized in the cytoplasm is transported into vacuoles and accumulated in its. In the light period the malate is effluxed from the vacuoles into cytoplasm, and then deacidification proceed.
