Enzymes that break down proteins into amino acids are called proteases. The process of breaking down proteins is called proteolysis. It is also called proteolytic or systemic enzyme. Protease enzymes digest protein-rich foods. For example, pepsin, trypsin, erepsin, papain etc. Uses or importance of protease are-
(i) Protease enzymes are used to improve bread quality.
(ii) It is used to control blood clotting.
(iii) It has uses in the preparation of medicines.
(iv) It breaks down animal carcasses and releases nitrogen and carbon into the environment.
(v) Protease enzymes are used in biological research.
