Table 1. Structures, IC50, Ki, and ΔGBind of PPIs.
IC50 is the concentration of PPIs required to inhibit 50% of the recombinant TE activity, as measured using the 4-MUH fluorogenic assay.
Ki, the inhibition constant, was calculated from the IC50 using the Cheng–Prusoff equation.37
ΔGBind, the binding free energy, was calculated by Poisson–Boltzmann surface analysis (PBSA), where ΔGbind = Gcomplex – GTE – GPPI and G = Gsolute + Gsolvent.
