The change in the binding free energy (Inline graphic) data obtained from replica exchange Monte Carlo (REMC) simulations (symbols) are shown as a function of the crowder packing fraction (ϕ) for different protein–crowder interaction strengths ranging from a purely repulsive interaction εr = 1.69k B T (a) to attractive interactions for the cytochrome c/cytochrome c peroxidase (Cc/CcP) complex(b). R c Effective particle radius for a crowder size, εr  crowder–protein repulsive strength, solid lines the predictions of our crowding theory as described in the text
