Protein translation in nature always begins with an initiator transfer RNA (tRNA) carrying the amino acid methionine. This was circumvented in vitro with a reconstituted translation system utilizing initiator tRNA synthetically mischarged with the other natural amino acids. In addition, it was determined that this system could accommodate these non-methionine amino acids containing various N-alpha-acyl groups, many of which are useful for post-translational modification such as peptide cyclization.
