| + | NH-pi interactions between polar and aromatic residues are well distributed in proteins whose stabilizing effects have been investigated in globular and fibrous proteins. In order to gain structural insights into side chain NH-pi interactions, we solved a crystal structure of a collagen-like peptide containing Gln-Phe pairs. The Gln-Phe NH-pi interactions were further characterized by quantum calculations, molecular simulations, and structural bioinformatics. The analyses indicated that the NH-pi interactions are robust under various solvent conditions, can be distributed either on the protein surface or in its hydrophobic core and can form at a wide range of distances between residues. This study suggested that NH-pi interactions can play a versatile role in protein design, including engineering hydrophobic cores, solvent accessible surfaces, and protein-protein interfaces. | ||
