Methods of Making Polypeptides with Non-Standard Amino Acids Using Genomically Recoded Organisms

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A method of making a polypeptide including at least one covalent bond between a pair of reactive side chains of corresponding amino acids, wherein the covalent bond is insensitive to reduction is provided including genetically modifying a genomically recoded organism to express a corresponding synthetase, tRNA or synthetase/tRNA pair for translating mRNA encoding the corresponding amino acids having the reactive side chains into the polypeptide and to express the polypeptide including the at least one pair of the reactive side chains wherein the reactive side chains are oriented near one another when the expressed polypeptide is in a folded configuration, wherein the reactive side chains react to form the covalent bond that is insensitive to reduction.
