Protein Design

Getting to the bottom of the TIM barrel

Natural (βα)8-barrel proteins support diverse catalytic functions and are fertile scaffolds for engineering synthetic enzymes. The atomic-resolution structure determination of a computationally guided, de novo–designed symmetric barrel is a long-awaited advance that opens up new opportunities for enzyme design.
