Conformation of the N-terminal region of PrAMPs in the ribosome. (A) The N-terminal of Bac71–35 (brown) extends further than Onc112 (green) [PDB ID: 4Z8C (27)] into the A site of the 50S subunit, establishing interactions with H89 of 23S rRNA. (B) The N-terminal of Bac71–35 is not compatible with the presence of the CCA-end of an A-site tRNA (light blue) [PDB ID: 4Y4P (69)]. (C) The Asp2 residue at the N-termini of PrAMPs Pyrrhocoricin, Metalnikowin, Onc10wt, OncΔ15–19 and Onc112 [PDB ID: 4Z8C (27)] interact with the Watson–Crick edge of nucleotide G2553 in the 23S rRNA A-loop.
