WebDuring translation of mRNA, most codonsare recognized by "charged" tRNAmolecules, called aminoacyl-tRNAsbecause they are adhered to specific amino acidscorresponding to each tRNA's anticodon. In the standard genetic code, there are three mRNA stop codons: UAG ("amber"), UAA ("ochre"), and UGA ("opal" or "umber"). WebA range of antibiotic inhibitors that act within the peptidyl transferase center of the ribosome were examined for their capacity to perturb the relative positioning of the 3' end of P/P'-site-bound tRNA and the Escherichia coli ribosome.

WebThe ribosome has three binding sites for tRNAs: E (exit), P (peptide), and A (acceptor). Once tRNAs have given up their amino acids and are uncharged, they leave the ribosome through the E site. The A site accepts incoming charged tRNAs and the growing polypeptide chain resides in the P site. The initiator tRNA begins in the P site.
