Abstract
Unnatural amino acids can be incorporated into proteins or peptides by a variety of existing methods. Peptide synthesis (1–5) and semisynthetic methods (6–10) have been used to substitute novel amino acids into small proteins (<10 kDa) and peptides (11). Solvent accessible, reactive amino acid side chains have also been modified by chemical means (12–18). Modified amino acids have been uniformly incorporated into peptides and proteins with functional analogs of aminoacyl transfer RNAs (tRNAs) (19–21). Furthermore, several unnatural amino acids have been incorporated into dipeptides through the use of chemically misacylated tRNAs (22,23). However, these methods all suffer either from nonselective introduction of the novel amino acid or from size restrictions on the protein of interest.
