A Native trinucleotide CCA. B C-puromycin (CPmn), a ribosomal A-site analog consisting of a cytidine monophosphate covalently linked to the aminonucleoside puromycin. C Native dinucleotide CA. D Puromycin (Pmn), an aminonucleoside mimicking the ribosomal A-site substrate. E The full-length 23S rRNA from T. thermophilus. The red highlights denote atoms potentially involved in the formation of the tetradentate chelation motif.
