abstract：:The eukaryotic ribosomal protein S15 is a key component of the decoding site in contrast to its prokaryotic counterpart, S19p, which is located away from the mRNA binding track on the ribosome. Here, we determined the oligopeptide of S15 neighboring the A site mRNA codon on the human 80S ribosome with the use of mRNA ...
