Only recently has it been established that a tripeptide in the bacterial release factors (RFs), RF1 and RF2, is responsible for the stop codon recognition. This functional mimic of the anticodon of tRNA is referred to as a tripeptide ‘anticodon’ or a tripeptide discriminator. Here we review the experimental background and process leading to this discovery, and strengthen functional evidence for the tripeptide determinant for deciphering stop codons in mRNAs in prokaryotes.
