Figure 8

Close-up view of the Pop5-RPP30 binding interface. RPP30 is green and the two Pop5 subunits are red and blue. The backbone of α8 in RPP30 is shown as sticks with the amide nitrogen and proton atoms shown in blue and white, respectively. The sidechains of aromatic residues from Pop5 and RPP30 near α8 in RPP30 are shown as sticks. Electronic ring currents from such aromatic residues can result in large chemical shift perturbations for amides in the protein-protein interface.
