DTT activates Escherichia coli

Application

Application Comment Organism
biotechnology misacylation of suppressor tRNAPhe CUA by the PheRS mutant A294G with 4-iodo-L-phenylalanine might be useful in application in protein engineering since an aryl iodide tag on proteins can be used for site-specific functionalization of proteins, used for cell-free protein synthesis as a stoichiometric reagent, overview Escherichia coli
