One of three such binding sites, the A-site is the first location … Webb9 maj 2024 · The A-site is where aminoacyl t-RNA enters the ribosome. The P-site is a the point where the peptidyl tRNA (the peptide bond between two amino acid residues attached to one t-RNA molecule) is formed in the ribosome. Where is the E site found? The A and P sites are the traditional tRNA binding sites on the ribosome (see Figure 1).
