    The System of Catalysis. Within the superimposed frameworks of IdeS, papain, and cathepsin B, the catalytic cysteine (Cys-94a€“Ser, Cys-25, and Cys-29, correspondingly) and histidine (His-262, His-159, and His-199) residues align perfectly. Hence Cys-94a€“Ser in IdeS is found at N-terminal region of helix I±1 during the software between the L and roentgen domains. To show the higher level of similarity regarding the general geometry of catalytic triad, an extra fitting with respect to the productive website is done (Fig. 2).
