The design of DNA binding domains based on the Cys2His2 zinc finger motif has proven to be a successful strategy for the specific recognition of novel DNA sequences. Although considerable effort has been devoted to the generation of zinc finger proteins with widely varying DNA-binding preferences, only a limited number of potential DNA binding sites have been targeted with a high degree of specificity. These restrictions on zinc finger design appear to be a consequence of the limited repertoire of side-chain lengths and functionalities available with the 20 proteinogenic amino acids. To demonstrate that these limitations can be overcome through the use of "unnatural" amino acids, expressed protein ligation was employed to incorporate the amino acid citrulline into a single position within a three-zinc finger protein. As anticipated, the resulting semisynthetic protein specifically recognizes adenine in the appropriate position of its binding site.
