The solution structure of the second PDZ domain from human phosphatase hPTP1E in complex with a C-terminal peptide from the guanine nucleotide exchange factor RA-GEF-2 has been determined using 2D and 3D heteronuclear NMR experiments. Compared to previously solved structures, the hPTP1E complex shows an enlarged interaction surface with the C terminus of the bound peptide. Novel contacts were found between the long structured beta2/beta3 loop of the PDZ domain and the sixth amino acid residue from the C terminus of the peptide. This work underlines the importance of the beta2/beta3 loop for ligand selection by PDZ domains.
