To guarantee specific tRNA and amino acid pairing, several aminoacyl-tRNA synthetases correct aminoacylation errors by deacylating or "editing" misaminoacylated tRNA. A previously developed variant of Escherichia coli tyrosyl-tRNA synthetase (iodoTyrRS) esterifies or "charges" tRNA(Tyr) with a nonnatural amino acid, 3-iodo-l-tyrosine

Non-natural amino acids have been genetically encoded in living cells, using aminoacyl-tRNA synthetase-tRNA pairs orthogonal to the host translation system. In the present study, we engineered Escherichia coli cells with a translation system orthogonal to the E. coli tyrosyl-tRNA synthetase

A suppressor tRNA(Tyr) and mutant tyrosyl-tRNA synthetase (TyrRS) pair was developed to incorporate 3-iodo-L-tyrosine into proteins in mammalian cells. First, the Escherichia coli suppressor tRNA(Tyr) gene was mutated, at three positions in the D arm, to generate the internal promoter

Beta cell dysfunction accompanies and drives the progression of type 2 diabetes mellitus (T2D), but there are few clinical biomarkers available to assess islet cell stress in humans. Secretagogin, a protein enriched in pancreatic islets, demonstrates protective effects on beta

We have developed a rapid, straightforward, one plasmid dual positive/negative selection system for the evolution of aminoacyl-tRNA synthetases with altered specificities in Escherichia coli. This system utilizes an amber stop codon containing chloramphenicol acetyltransferase/uracil phosphoribosyltransferase fusion gene. We demonstrate the
