Figure 4. Cartoon representation of the common dimer structures observed in crystal forms of EspG₃.

Superimposed subunits are in green with the buried surface area of the dimer interface indicated above the structure. The wing-shaped dimers are present in the asymmetric unit of EspG_3msm (PDB ID 4L4W) and EspG_3msm (PDB ID 4W4J) or generated by crystallographic symmetry in EspG_3msm (PDB ID 4RCL). The β8-mediated dimer is present in the asymmetric unit in EspG_3msm (PDB ID 4RCL) and generated by crystallographic symmetry in EspG_3msm (PDB ID 4W4J [27]).
