Metalloprotease
Metalloprotease — A protease enzyme that uses a metal ion (usually zinc) in its catalytic mechanism, involved in extracellular matrix remodeling.
What Is a Metalloprotease?
A metalloprotease is a protease that uses a metal ion (usually Zn²⁺) in its catalytic mechanism to activate a water molecule for peptide bond hydrolysis. Major metalloprotease families include matrix metalloproteinases (MMPs, ECM remodeling), ACE (angiotensin converting enzyme), and neprilysin (enkephalin/natriuretic peptide degradation).
Significance
- MMPs: Degrade collagen and ECM. MMP substrates are peptide sequences used in responsive hydrogels
- ACE: Converts angiotensin I to angiotensin II. ACE inhibitors are blockbuster drugs
- Inhibition: Chelating groups (hydroxamic acid, thiol) in peptide inhibitors coordinate the active-site zinc
