Intermolecular interactions between nsp14 and nsp10. Zinc ions are represented as gray spheres in A–C. (A) The Nsp14 ExoN domain (green) is stabilized by nsp10 (red). Two regions of nsp10 (boxed) contribute major interactions with nsp14. Zn1^nsp10, the first zinc ion of nsp10. (B and C) Interaction details by regions 1 (B) and 2 (C). Hydrogen bonds between residues are shown by dashed lines. Residues of nsp14 and nsp10 involved in interaction are displayed as green and red sticks, respectively. (D) Schematic representation of the contacts between nsp10 and nsp14.
