From: PDZ domains and their binding partners: structure, specificity, and modification
Each residue in the PDZ-bound ligand adopts a specific conformation. (A) Distribution of (ϕ,ψ) angles of each residue of the PDZ-bound ligand. Dataset were from PDBsum http://www.ebi.ac.uk/pdbsum/. (B) The orientation of each residue in the side chain of the PDZ ligand in case of a free carboxy-terminal peptide and the internal sequence from PSD-95/nNOS and Par-6/Pals1 complex [65, 69, 185, 186].
