An Escherichia coli suppressor tRNA(Phe) (tRNA(Phe) (CUA)) was misacylated with 4-iodo-L-phenylalanine by using the A294G phenylalanyl-tRNA synthetase mutant (G294-PheRS) from E. coli at a high magnesium-ion concentration. The preacylated tRNA was ad

An unnatural base pair of 2-amino-6-(2-thienyl)purine (denoted by s) and pyridin-2-one (denoted by y) was developed to expand the genetic code. The ribonucleoside triphosphate of y was site-specifically incorporated into RNA, opposite s in a template

A variety of unique codons have been employed to expand the genetic code. The use of the opal (UGA) codon is promising, but insufficient information is available about the UGA suppression approach, which facilitates the incorporation of non-natural a
