(a) Per-residue RMSFs for ZnF1 in Model 1 to Model 4. (b) The three-dimensional structure diagram of ZnF1 (4OPX). The interaction interface of ZnF1/DSB and ZnF1/CAT are represented by blue and red, respectively, and the corresponding residues are shown in blue and red. (c) Per-residue energy contribution spectra of ZnF1 on the surface of ZnF1/DSB for Model 1 to Model 4. Red, blue, green, and yellow bars represent Lig1, Lig2, Lig3, and without ligand binding to CAT (marked as WLig). (d) Per-residue energy contribution spectra of ZnF1 on the surface of ZnF1/CAT for Model 1 to Model 4. Red, blue, green, and yellow bars represent Lig1, Lig2, Lig3, and WLig.</p
