• PubMed Abstract: 
  

  A great challenge to biologists is to create proteins with novel folds and tailored functions. As an alternative to de novo protein design, we investigated the structure of a randomly generated protein targeted to bind ATP. The crystal structure reveals a novel alpha/beta fold bound to its ligand, representing both the first protein structure derived from in vitro evolution and the first nucleotide-binding protein stabilized by a zinc ion.
