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.
