ElongationStep 2: Peptide bond formation• The peptidyl transferasecatalyzing the formation ofpeptide bond by transferring N-formylmethionyl group to theamino group of the secondamino acyl-TRNA in the A site –forming dipeptidyl-TRNA• The uncharged (deacylated)TRNA fmet remains bound tothe P site40
ElongationStep 3: Translocation• The ribo moves one codon towards the 3’endof the MRNA• This movement shifts the anticodon of thedipeptidyl Trna (which still attached to the2 nd codon from A to P site• At the same time the deacylated Trna isshifted from P to E site, and Trna is releasesinto the cytosol• The third codon of the mrna now lies in the Asite and the 2 nd codon in the P site• Movement of rib along Mrna require EF-G(Translocases) and the energy is provided byhydrolysis of another molecule of GTP• The rib is now ready for next addition of aa41
