Abstract

Translation systems with four-base codons provide a powerful strategy for protein engineering and protein studies because they enable site-specific incorporation of non-natural amino acids into proteins. In this study, a caged aminoacyl-tRNA with a four-base anticodon was synthesized. The caged aminoacyl-tRNA contains a photocleavable nitroveratryloxycarbonyl (NVOC) group. This study showed that the caged aminoacyl-tRNA was not deacylated, did not bind to EF-Tu, and was activated by light. Photo-dependent translation of an mRNA containing the four-base codon was demonstrated using the caged aminoacyl-tRNA.
