MONO CHARGING SYSTEM FOR SELECTIVELY INTRODUCING NON-NATIVE AMINO ACIDS INTO PROTEINS USING AN IN VITRO PROTEIN SYNTHESIS SYSTEM

摘要

This invention provides for a novel means of incorporating non-native amino acids into preselected positions of a protein using a cell-free synthesis system. The methods involve the use of non-orthogonal, native isoaccepting sense tRNAs that are encoded by the genetic code. Such methods allow for numerous non-native amino acids to be incorporated through the use of sense codons without having to rely upon orthogonal tRNA-synthetase pairs.
