Compared to the reaction in solution, the ribosome accelerates peptidebond formation y107-fold. What are the roles of substrate-assisted catalysis and proximity effects in peptidebond formation by the ribosome? The active site of the ribosome is composed of two layers of conserved nucleotides with distinct roles in peptidebond formation and peptide release. The issue is not energy, but the formation and stability of the peptidebond from which much of the polymer-chemical architecture of life springs. Clearly, it would be desirable to investigate the mechanism of peptidebond formation in this system, which is the biologically relevant one. The ribosome accelerates peptidebond formation by 107-fold relative to the uncatalyzed reaction. However, analysis by single-molecule techniques suggests that it is in fact the formation of the first peptidebond that results in these conformational changes. The best explanation is a photoinduced intramolecular electron transfer from the absorbing site to the peptidebond, followed by its scission. Peptidebond formation by in vitro selected ribozymes. In recent years, new insights into the mechanism of peptidebond formation were obtained due to the enormous progress in structural, biochemical, and genetic studies of the ribosome. Peptidebond formation is the fundamental reaction of ribosomal protein synthesis. Peptidebond formation does not involve acidbase catalysis by ribosomal residues. Enteropeptidase is produced by the mucosa of duodenum and it cleaves the peptidebond of trypsinogen after residue 15, which is a lysine.

The outer loop is formed by the normal peptidebond of the carboxyl terminus to the amino terminus of the peptide chain.

For simplicity and efficiency, often only the alpha carbon positions are considered, since the peptidebond has a minimally variant planar conformation.

The prosequence then acts as a molecular chaperone and leads to autocleavage of the peptidebond linking pro and mature sequences.
