The Zika NS2B-NS3 protease is susceptible to allosteric inhibition by natural products. (A)Chemical structures of six natural products identified to allosterically inhibit the Zika NS2B-NS3 protease. (B) The crystal structure (PDB code of 5LC0) of the Zika NS2B-NS3 protease determined with an active site inhibitor cn-716 (in spheres); onto which six natural products (in sticks) were docked. (C) The Zika NS2B-NS3 protease in complex with cn-716 and six natural products in which NS2B is displayed in ribbon and NS3 protease domain in the electrostatic potential surface. (D) Expanded binding pockets of the Zika NS2B-NS3 protease in complex with six natural products.
