| X-ray crystallographic signature of supramolecular triple helix formation from a water soluble synthetic tetrapeptide (2005) | |||||||||
Abstract | |||||||||
| Single crystal X-ray diffraction studies on the water soluble, synthetic tetrapeptide Tyr(1)-Aib(2)-Tyr(3)-Val(4) with a non-coded amino acid residue (Aib: $\alpha$-amino isobutyric acid) reveal that the peptide adopts an "S"-shaped molecular structure which self-assembles to form a supramolecular triple helix using various non-covalent interactions including water mediated hydrogen bonds in the solid state. | |||||||||
