Figure 5. Stoichiometry of interaction of mEndopin 1 with trypsin (○) and HLE (●).
Regression analysis of the linear part of the curves cross the x-axis at 20 nM and 50 nM. These concentrations correspond to the amount of mEndopin 1 needed for a total inhibition of trypsin (20 nM) and elastase (50 nM), indicative of a 1:1 enzyme/inhibitor ratio.
