FIGURE 4.
Effects of a heme inhibitor (potassium cyanide) on the (A) peroxidase and (B) chaperone activities of AtAPX1 protein. To inhibit heme, we incubated AtAPX1 protein with (○) 0 mM, (▲) 2 mM, (◼) 4 mM, and (◆) 8 mM potassium cyanide at 4°C for 15 min. (●) Control indicated measuring the activity without AtAPX1 protein.
