Fig. 4: Details of the molecular interactions between JUNV L and Z protein.

a A cartoon representation of JUNV L–Z complex structure is shown, with L shown in gray and Z in blue. The black boxes indicate the magnified view of the interactions between L and Z. b, c Magnified views of interaction interfaces between L and Z. The representative residues involved in the interaction are shown, main chain or side chains involved in hydrogen bonds or hydrophobic interactions are shown as sticks, with oxygen, nitrogen and sulfur atoms shown in red, blue and yellow, respectively. Hydrogen bonds are depicted as black dashed lines. d L and Z are shown as molecular surfaces colored by electrostatic potential from red to blue, negative to positive, respectively. The surface of each protein is shown in an open-book representation. The approximate binding interface is outlined by a black dashed line.
