WebThe optimization of GAL4 reporters is described, and the positive and negative selection of active Escherichia coli tyrosyl-tRNA synthetase (EcTyrRS)/tRNA (CUA) is demonstrated. Importantly, both selections can be performed on a single cell and with a range of stringencies. This method will facilitate the isolation of a range of aminoacyl-tRNA ... WebRecently, we showed that EcTyrRS can be engineered using a facile E. coli based selection system, in a strain where the endogenous tyrosyl pair has been substituted with an archaeal counterpart. However, a significant cross-reactivity between the UAG-suppressing tRNACUAEcTyr and the bacterial glutaminyl-tRNA synthetase limited the scope of this ...

Recently, some aaRSs evolved to charge UAAs in bacteria were found to be polyspecific, i.e., they are able to accept a variety of UAAs as substrates, while excluding the canonical 20 amino acids (16). The availability of such a polyspecific aaRS for use in mammalian cells would be at- size or weight of saturn
