From: Inhibition of SARS-CoV-2 3CL protease by the anti-viral chimeric protein RetroMAD1

Binding of RetroMAD1 with 3CLpro. (A) Structure of SARS-CoV-2 3CLpro monomer (PDB ID 6LU7). (B) Red colour indicates the active site of SARS-CoV-2 3CLpro (Novak et al., 2021). The catalytic dyad, His41 and Cys145 depicted in yellow and dark blue respectively. The binding complex of 3CLpro with (C) RetroMAD1, (D) Andrographolide, (E) Ivermectin and (F) Remdesivir. Figure was made by using Pymol.
