Interface between PPE4mt and EspG3mm.
A, surface representation of PPE4mt and EspG3mm shown in an “open book” view. Interacting residues are colored in blue (PPE4mt) and orange (EspG3mm), with mutated residues highlighted in light orange (PPE4mt) and light blue (EspG3mm). Another view of PPE4mt, related by a 180° rotation, is also shown. B, the same orientations as A but with the surface colored according to surface potential as calculated by APBS (32). The interacting residues are highlighted with a black outline.
