WebbEach of these nucleotides lies within the peptidyl transferase loop region of the 23S rRNA. Cross-links were also formed with ribosomal proteins L27 (strong) and L33 (weak), as … WebbThe P site is where the peptidyl tRNA is formed in the ribosome. And the E site which is the exit site of the now uncharged tRNA after it gives its amino acid to the growing peptide chain. The selection of an initiation site (usually an AUG codon) depends on the interaction between the 30S subunit and the mRNA template.
