Differential Susceptibilities of Tonoplast ATPase and PPase to Irreversible Inhibition by Chaotropic Anions
Isolated intact vacuoles and tonoplast vesicles are distinguished from other endomembranes by their possession of a NO 3 − -inhibited, azide-insensitive ATPase (tp-ATPase; Rea et al., 1987). However, information concerning the mode of action of NO 3 − is scant.
