FIGURE 7.
Crystal structure of RPP1 plant TIR-domains showing TIR-TIR interfaces. Three of four RPP1 TIR-domain units shown (PDB ID: 5TEB). The AE (SH 108-109) and DE interfaces (G 229) are shown purple and red, respectively, while putative catalytic glutamate E164 shown orange. Connecting loop above putative catalytic glutamate is colored green. Potential loop interactions between putative ionic pairs of adjacent RPP1 monomers (residues E128 – K234, and R129 – E238) shown with dashed yellow lines. Distances between putative ionic pairs measured using Pymol: E128 to K234 (8.0 Å) and R129 to E238 (4.8 Å).
