Fig. 5: Proposed two-step mechanism of PET degradation by the codisplay system.

a MD simulation of the dynamic process of PET adsorption by the codisplay system. b Hydrophobic interaction between PET substrate and HFBI. c IFD analysis of the conformational fitting for the codisplay system during hydrolysis. Each domain is assigned a unique color. The active sites are marked with blue spheres. 4PET are marked with sticks.
