    Protease - Wikipedia

    A protease is an enzyme that catalyzes proteolysis, the breakdown of proteins into smaller polypeptides or single amino acids. They do this by cleaving the peptide bonds within proteins by hydrolysis, a reaction where water breaks bonds. Proteases are involved in many biological functions, including digestion of eaten proteins, protein catabolism, and cell signalling. Without additional helping mechanisms, …
