Figure 3.

Intermolecular interactions and quality of ternary complex structure. (a) Schematic figure detailing the interactions between the main chain and side chains of the D-AKAP2_AKB, the RIIα D/D monomer and the PDZK1_D4 domain. Solid and dashed arrows indicate the hydrophobic and polar interactions respectively. (b) Quality of the electron density maps to 3.8 Å resolution. Stereoview illustrating the quality of the 2F_o – F_c final electron density map contoured at 1σ for the ternary complex. The figure is centered on the D-AKAP2_AKB: RIIα D/D interface, which shows relatively weaker density compared with the PDZK1_D4 molecules. The final, refined model is represented as ribbons and labeled.
