  • The 23S rRNA is a 2,904 nucleotide long (in E. coli) component of the large subunit (50S) of the bacterial/archean ribosome and makes up the peptidyl transferase center (PTC). The 23S rRNA is divided into six secondary structural domains titled I-VI, with the corresponding 5S rRNA being considered domain VII. The ribosomal peptidyl transferase activity resides in domain V of this rRNA, which is also the most common binding site for antibiotics that inhibit translation, making it a target for ribosomal engineering. A well-known member of this antibiotic class, chloramphenicol, acts by inhibiting peptide bond formation, with recent 3D-structural studies showing two different binding sites depending on the species of ribosome. Numerous mutations in domains of the 23S rRNA with Peptidyl transferase activity have resulted in antibiotic resistance. 23S rRNA genes typically have higher sequence variations, including insertions and/or deletions, compared to other rRNAs. The eukaryotic homolog of the 23S LSU rRNA is the 28S ribosomal RNA, with a region filled by the 5.8S ribosomal RNA. (en)
  • El ARN ribosomal 23S, a veces abreviado como ARNr 23S o simplemente 23S, es un componente de la subunidad de los ribosomas de procariotas. Bioquímicamente, se trata de una cadena de ácido ribonucleico que, en Escherichia coli, posee 2.904 nucleótidos de longitud. En él radica la actividad peptidil transferasa del ribosoma, esencial en la biosíntesis de proteínas. El agente antimicrobiano denominado cloramfenicol es un inhibidor enzimático de la traducción precisamente porque bloquea los rediduos aminoacídicos implicados en el proceso de generación del enlace peptídico.​ (es)
