More dilution induces a dissociation of the native tetramer to a less active dimer, preincubation of the dilute enzyme with phosphoenolpyruvate stabilizes the tetramer while the presence of malate induces dimer formation, glucose 6-phosphate induces tetramer formation of the dilute enzyme, both the substrate phosphoenolpyruvate and the activator glucose 6-phosphate stabilize the active tetramer via binding and interaction at an activator site separate from the active site Crassula argentea
