Lineweaver-Burk plots of the ATPase activities of wt Cdr1 and A713P in response to increasing inhibitor concentrations. (A) Top, wt Cdr1 with FK506. Concentrations were 0 (green diamond), 0.5 μM (blue square), and 1 μM (magenta triangle). Bottom, A713P with FK506. Concentrations were 0 (green diamond), 1 μM (blue square), and 10 μM (magenta triangle). (B) Top, wt Cdr1 with enniatin B. Concentrations were 0 (green diamond), 0.1 μM (blue square), and 0.5 μM (magenta triangle). Bottom, A713P with enniatin B. Concentrations were 0 (green diamond), 0.1 μM (blue square), and 10 μM (magenta triangle). (C) Top, wt Cdr1 with beauvericin. Concentrations were 0 (green diamond), 0.2 μM (blue square), and 0.5 μM (magenta triangle). Bottom, A713P with beauvericin. Concentrations were 0 (green diamond), 0.1 μM (blue square), and 2 μM (magenta triangle). (D) wt Cdr1 with oligomycin. Concentrations were 0 (green diamond), 0.5 μM (blue square), and 1 μM (magenta triangle). (E) wt Cdr1 with vanadate. Concentrations were 0 (green diamond), 0.5 μM (blue square), and 2 μM (magenta triangle).
