• PubMed Abstract: 
  

  A designer monomeric protein with a beta alpha beta fold--two parallel beta strands connected by an alpha helix (see structure)--was constructed solely from coded amino acids. The high thermal stability of the structure is due to a large extent to tryptophan-tryptophan interactions between the two beta strands.
