WebApr 1, 2012 · Peptide bond formation. The formation of a peptide bond between two amino acids involves two steps. The first step is the activation of the carboxyl group of one residue; this step accounts for a key step in the synthesis of a large number of bioorganic molecules, in particular during peptide synthesis ( Sheehan and Hess, 1955). WebThe formation of each peptide bond is catalyzed by peptidyl transferase, an RNA-based enzyme that is integrated into the 50S ribosomal subunit. The energy for each peptide bond formation is derived from GTP … WebPeptide bonds are formed when the amine group of one amino acid binds with the carbonyl carbon of another amino acid.
