In vivo incorporation of alkynyl amino acids into proteins in eubacteria

摘要

The invention relates to orthogonal pairs of tRNAs and aminoacyl-tRNA synthetases that can incorporate alkynyl amino acids such as para-propargyloxyphenylalanine into proteins produced in a cubacteria host such ass E. coli. The invention provides novel orthoghonal synthetases methods for identifying and making the novel synthetases methods for producing proteins containing alkynyl amino acids, and cellular translation systems.
