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 … Zobacz więcej In general, rRNA has an essential function of peptidyl transferase. The stimulating core of the ribosome plays role in the peptide bond configuration. Both peptidyl-tRNA and aminoacyl-tRNA are important for protein … Zobacz więcej The 23S ribosomal RNA is composed of six domains forming a complex network of molecular interactions. A central single-stranded region connects all of the domains through base-pairing of the two halves, forming Helix 26a.
