The crystal structure of human NHERF PDZ1 bound to the carboxyl-terminal peptide QDTRL has been determined at 1.7-A resolution. The structure reveals the specificity and affinity determinants of the PDZ1-CFTR interaction and provides insights into carboxyl-terminal leucine recognition by class I PDZ domains. The peptide ligand inserts into the PDZ1 binding pocket forming an additional antiparallel beta-strand to the PDZ1 beta-sheet, and an extensive network of hydrogen bonds and hydrophobic interactions stabilize the complex. Remarkably, the guanido group of arginine at position -1 of the CFTR peptide forms two salt bridges and two hydrogen bonds with PDZ1 residues Glu(43) and Asn(22), respectively, providing the structural basis for the contribution of the penultimate amino acid of the peptide ligand to the affinity of the interaction."xsd:string |
