title: Recombination of fragmented proteins.
abstract: Directed evolution is a powerful method for generating novel molecules with desirable properties. In developing a new sensor to screen for protein-protein interactions, Tafelmeyer et al. report a clever strategy to evolve heterodimeric "split proteins" from a monomer in this issue of Chemistry & Biology.
