A novel interdomain interface in crystallins: structural characterization of the βγ-crystallin from Geodia cydonium at 0.99 Å resolution

The X-ray crystal structure of geodin is reported.

Three-dimensional domain swapping and supramolecular protein assembly: insights from the X-ray structure of a dimeric swapped variant of human pancreatic RNase

The intriguing crystal organization of the domain-swapped dimer of a human pancreatic ribonuclease variant indicates that the protein can form fibrils in solution. They were observed and characterized by atomic force microscopy. The importance of domain swapping in inducing native-like fibril formation is highlighted.

Duplex-quadruplex motifs in a peculiar structural organization cooperatively contribute to thrombin binding of a DNA aptamer

The structure of the thrombin-HD22-27mer complex, solved at 2.4 Å resolution, reveals an intriguing duplex-quadruplex folding of the aptamer, which extensively interacts with the exosite II of the protein.
