Replacing amino acids in translation: expanding chemical diversity with non-natural variants.

Abstract excerpt

Here, we describe a strategy for synthesis of peptides with multiple unnatural amino acids (UAAs) using in vitro translation. Our method involves removing a natural amino acid and replacing it with an UAA variant in a reconstituted translation system. Whereas other systems require engineered components or chemical synthesis to charge UAAs onto tRNAs prior to translation, our strategy utilizes the wild-type...
