Figure 3. Determination of the mode of inhibition of RgpB (A) and Kgp (B) by Epimedokoreanin B (compound 8).
The velocity (v) of the reaction was determined at the substrate concentration [S] in the range from 20 µM to 100 µM in the presence of various concentrations (0–10 µM) of Epimedokoreanin B and the ratio of [S]/v for each inhibitor concentration [I] was plotted (the
