Schematic model for the catalytic process of SARS-CoV Mpro. Substrate binding triggers the monomer-dimer equilibrium to favor the active protomer (square). The active protomer now is prompt to associate, forming the catalytic-competent dimer. After the catalytic cycle, the associated dimer will dissociate again to form the inactive protomer (circle).
