Catalysis
Catalysis — The acceleration of a chemical reaction by a substance (catalyst) that is not consumed in the process, fundamental to enzyme-mediated peptide reactions.
What Is Catalysis?
Catalysis is the acceleration of a chemical reaction by a catalyst that is not consumed. In peptide science, enzyme catalysis drives proteolytic processing, post-translational modification, and native chemical ligation. Catalytic peptides (peptide-based artificial enzymes) are an emerging research area using designed peptide sequences to mimic enzyme active sites.
Peptide-Based Catalysis
- Histidine-containing peptides: Imidazole side chain provides acid-base catalysis mimicking esterases
- Metallopeptides: Designed zinc- and copper-binding peptides with hydrolytic or oxidative catalytic activity
- Sortase: Bacterial enzyme catalyzing transpeptidation for peptide ligation
