Stepwise introduction of stabilizing mutations reveals nonlinear additive effects in de novo TIM barrels.

Abstract excerpt

Over the past decades, the TIM-barrel fold has served as a model system for the exploration of how changes in protein sequences affect their structural, stability, and functional characteristics, and moreover, how this information can be leveraged to design proteins from the ground up. After numerous attempts to design de novo proteins with this specific fold, sTIM11 was the first validated de novo design of an...
