| Popis: | One sequence encoding two structures Most proteins have stable, folded structures, but there are rare examples of metamorphic proteins that can switch between two different folds that may each have a different function. Dishman et al. investigated the evolution of XCL1, which is a member of the chemokine family that interconverts between the chemokine fold and a second, noncanonical fold that forms dimers. The authors used nuclear magnetic resonance spectroscopy to investigate the structures of inferred evolutionary ancestral sequences. Their results suggest that XCL1 evolved from an ancestor with the chemokine fold and then transitioned to prefer the noncanonical fold before reaching the modern-day metamorphic protein.
