Dimerization is guided by interactions established by residue Glu166 of one monomer with the NH2 terminus (N-finger) of the other (Shi and Song, 2006). In addition to the active site, the experimental structure of 3CLpro in complex with inhibitor AT7519 reveals a large allosteric pocket (...

Interestingly, E166 side chain interacts with Serine 1 NH2-terminal of the second monomer11,48. This salt bridge interaction minimizes the conformational flexibility of E166 backbone and assists in generating the correct orientation of the substrate binding site, which explains the importance of ...
The structure of the 3CL Mpro protein (Fig. 1) embraces three domains: (i) domain I (residues 8 to 101); (ii) domain II (residues 102 to 184) with the catalytic site in an antiparallel β-barrel structure; and (iii) domain III (residues 201 to 303) of each monomer forms the in...

Fig. 1: The crystal structure of ligand free Mpro is amenable to X-ray fragment screening. a Cartoon representation of the Mpro dimer. The nearmost monomer is shown with secondary structure features coloured to demarcate domains I, II, and III, in orange, cyan, and violet respectively. The...
The C-terminal domain of SARS-CoV main protease (Mpro-C) can form 3D domain-swapped dimer by exchanging the α1-helices fully buried inside the protein hydrophobic core, under non-denaturing conditions. Here, we report that Mpro-C can also form amyloid fibrils under the 3D domain-swappable...
an exact determination is prevented by the inability to fit the isotherms to a monomer:dimer two-state model. That notwithstanding the data clearly indicate that the equilibrium constant is at least one order of magnitude larger compared to the reduced protein. The shift of the oligomeric equilibri...
